Microsoft Coding Interview: Process

How to Ace a Coding Interview by Thinking in Patterns

Microsoft is always looking for smart people, like all companies. But this company is looking for a candidate who is passionate about technology. During the coding interview at Microsoft, you probably wont be tested on the ins and outs of APIs, but you will have to write code on the board.

During the coding interview at Microsoft, you will first have a brief interview with a recruiter who will ask you a few questions to prepare yourself. Typically, your first interviewer will not ask you about coding and technical questions, but if you are asked about coding and technical questions, they will only serve to prepare you for your next rounds so that you are less nervous in the next round.

You will have the coding interview at Microsoft at the office itself, unlike many companies where you are interviewed in a conference room. But if the Covid-19 continues till your interview, you can have a virtual interview where you give an interview on a video call, but the entire process remains the same. On the day of your interview, you will have 4 to 5 interviews. Make sure to be nice with all your interviewers as they can fight for you to be hired or not.

Research Research And More Research

Begin by scrounging up all those juicy informative morsels you can get your hands on to give you a leg up during the interview itself.

Research the company

Dig through the companys official website to gain an understanding of what it is all about. Use Google to track down press releases, news articles, blogs and even social media posts about the company.

Combine all this researched info into the most up-to-date account of what the company is best known for or what it is focusing on lately, which will provide you with an arsenal of information for your own questions or talking points during the interview.

Find a current developer

Browse through the company directories and dig into social media connections to locate a current or previous developer from the company. While you dont want to force anyone into an uncomfortable situation, if the opportunity presents itself, getting in touch with one or two company developers can be a huge boon to your research endeavors. A company employee can provide a great deal of insight into the interview techniques the company uses as well as the day-to-day activities of the position for which you may be interviewing.

Try Out Mock Coding Interviews

Coding right in front of your interviewer can be a nerve-wracking experience especially if you have never done it before – which is why getting hands-on experience is so important.

interviewing.io is currently the best mock technical interview resource in the market. It allows you to book mock coding interviews with real Google and Facebook engineers, albeit anonymously. You could even book interviews for specific roles like Mobile, Front End, Engineering Management.

Describe The Runtime And Memory Usage

This is another step that looks great if you do it without being asked by your interviewer. Knowing the runtime and memory usage of code you write is incredibly important as it determines if your code is good enough for production. If you can, try going line by line to show you understand how to determine these values.

The Trouble With Technical Interviews They Aren’t Like The Job You’re Interviewing For

Interviewing for an engineering job in the tech world can mean youâll be asked all sorts of questions. Sometimes, the interview questions can be pretty straightforward: âTell me about a time that you have implemented an effective monitoring solution for a production system.â Other times, the questions are impossible to answer and designed to spark your creativity: âHow many windows are in New York City?â After passing the initial interview, the candidate graduates to the next tier of interviewing: The often-dreaded technical interview.

Final Thoughts On Improving

Thats a lot to keep in mind while doing an interview. As with any skill, practice is the best way to improve.

Practice the different aspects Ive described. Do mock interviews with friends or colleagues, and ask them to rate you on the criteria above.

Interview your friends. Its easier to spot mistakes and areas for improvement when youre on the other side of the table. This process can help you stay attentive to your strengths and weaknesses in interviews. Conducting interviews as an interviewer has been a key factor in making me a better interviewee over the years.

Do leetcode questions. Practice makes permanent. The point of doing leetcode is not to memorize solutions, its to recognize different types of problems. When you see a new question, youll be able to categorize it and draw on your knowledge to have an idea of which path to take, which edge cases might be an issue, which questions youll need to ask, and what kind of performance implications youll need to address.

What Concepts Are Emphasized During A Coding Interview

How to ace the whiteboard coding interview

Concepts frequently emphasized include arrays and strings, binary trees, dynamic programming, and linked lists. According to CoderPad, other common interview topics include breadth-first search algorithms, palindrome checker, and sorted lists of numbers. Interviewers may emphasize data structures and algorithms.

Common data structures tested include arrays, linked lists, stacks, and queues. Common algorithms tested include recursion, bubble sort, insertion sort, and binary search.

Of course, the interview topics will also depend on the role you are interviewing for and the skills and tools that will likely be needed for the job.

In addition to assessing your technical skills, the interviewer will also be watching for examples of creative thinking and the ability to receive and apply feedback. They may look for signs that tell them how you may fit in with the team and company culture, and judge your understanding of the role and the companys work.

Can You Tell Me A Bit About Your Experience

This is one of the most fundamental questions you should expect to answer in any coding interview and any interview at all, for that matter. The hiring manager will want to know about your experience and how well you can work in the companys environment.

This question is relatively open-ended, and having a good answer can feel overwhelming. One common tactic is to answer in a present, past, future format. Start by talking about what youre currently doing, how your past experience prepared you for the position and what you hope to be doing in the future. Mention any relevant projects, coding languages or other factors specific to the job youre interviewing for.

One way to answer this question using the present, past, future format could be:

At the moment Im working as a programmer for a medium-sized software development company. This is my first programming position, and I got started by working on open-source projects and completing a coding boot camp. My eventual goal is to learn more about software development and become a software engineer.

Did you know that if you dont have as much experience in programming as youd like, or dont know the necessary coding languages, there are options available to help you gain the expertise you need in just six months or less? Completing a coding boot camp provides hands-on experience in some of the industrys most valuable technologies, including HTML/CSS, JavaScript and React.js.

Preparing For Technical Interviews

Prospective engineers often face a challenge when it comes to preparing for the technical interview, largely because there is no playbook for how companies set them up technical. Itâs unclear whether to prepare by memorizing many different topics, or focusing on specific projects. Is it better to practice with a computer or a peer engineer? There are an overwhelming number of resources available online, but with little clarity as to what the standard is for a technical interview and little guidance from the company on what to expect, most of the time engineers start technical interviews in the dark.

Inconsistencies in the technical interview process isnât just a job candidate problem. In fact, many companies struggle to set up a technical interview process that is effective, equitable, and allows the hiring manager to compare candidates. The problem with technical interviewing compounds when a company is experiencing rapid growth.

Roles That Are Likely To Have Coding Interviews

Of course, the level of coding required does differ depending on the position. Check this YouTube video if youre interested in learning the differences between various DS roles. If you are looking for a data scientist role that falls into any of the categories below, the chances of encountering a coding interview are very high:

  • Data scientist roles with a heavy machine learning or modeling emphasis: For these kinds of roles, candidates are expected to work independently or closely with engineers to productionize machine learning, statistical, or optimization models. Such roles, though titled data scientist, are more similar to machine learning engineer or research scientist roles. A few examples of such jobs are Core Data Science at Facebook, Data Scientist Algorithms at Airbnb and Lyft, etc.
  • Companies in which data scientists are part of an engineering org: For such positions, there is a general expectation that every data scientist possesses sufficient programming proficiency. Robinhoods data scientist position is an example of this kind of role.
  • Data scientist roles at small to medium-sized tech companies: The environment in such companies tends to be fast-paced, and data scientists may wear multiple hats. In particular, they are required to demonstrate full-stack skills to get things done quickly and efficiently.

How to Ace that Coding Interview?

The topic of computer science is, by its very own nature, very dense, and the subject matter can be hard to digest. Pick a particular area, increasing the difficulty as you go, and try to solve 23 coding questions per day. Anymore than this, and you may start to lose your drive to study, begin skipping days, etc., and a good study plan will immediately unravel.

Dedicate one day to reviewing that weeks questions and study topics. This is extremely important for material retention. Take one day off per week to give your brain a break. This is important, everyone needs to rest and reset.

Lets say you devote 6 weeks to interview preparation. At 6 days per week, with 1 day dedicated to review , youre going to solve 60 questions , or 90 questions . Thats pretty serious progress, and 6 weeks will go by in a blur! Again, dial the time up or down as needed.

Dont cram, unless absolutely necessary! Re-read the section on properly preparing if needed. A crash course will yield marginal results at best, failure at worst.

Define Your Inputs Outputs And Edge Cases

After you’ve clarified the problem, it’s time to start finding a solution. Write the inputs or functions that’ll lead you to a solution, and explain what outputs you expect them to produce. You’ll also want to address any edge cases as you find them.

In the video above, Farish shares an example. Imagine that your task involved merging two sorted arrays to a new sorted output array. In this case, your edge cases would be duplicate numbers in the two input arrays.

Onsite Interview And Whiteboard Challenge

Now weve arrived at the most intimidating part of the entire tech interview process. At tiny startups, onsite technical interviews might be a lot less formal than at bigger companies. Heck, there may not even be a whiteboard to do a coding exercise on! Still, whatever the company size, it never hurts to do coding interview preparation so youre ready for any situation that may arise.

What to do during the onsite technical interview + whiteboard challenge

1. Ask clarifying questions before you even start writing code.

I appreciate it when someone takes the time to evaluate the question he faces in the interview, says Refael . It shows me that this person is calculated and rather than just writing code, he sees the whole picture.

Ask questions around assumptions of the question, and try to reason about the question from a bottom-up perspective, adds Chris.

2. Talk through your code to give the interviewer a window into your thoughts.

What happens in a technical interview is as much about the journey as the destination. Its designed to test a candidates communication and problem-solving skills, says Refael. More important than the solution is how they work at getting the solution. Can they articulate their thoughts while writing out the code on the whiteboard? Are they putting together a clear response to the question?

3. Speak clearly and precisely.

Dont Forget Soft Skills

Other than hard skills, soft skills are unavoidable in almost every job role. To ace the interview, you need the power to speak with confidence and skills to explain your point. You should understand that soft skills are not just a way we communicate it is our thought process, quick decision making, problem-solving, and leadership skills.

How well are you reacting to a stressful situation?Are you panicking during the interview?Are you failing to put forward your point?

Because of how we traditionally perceive the role of a developer, it is assumed that you dont require soft skills. While that may have been the case five years back, we need to have soft skills to grow with the company.To improve your soft skills, you can talk about your code and explain it in front of the mirror. Try to make your language and explanation informative yet straightforward.
