Phases Of A Coding Interview
Congratulations, you are ready to put your skills to practice! In a coding interview, you will be given a technical question by the interviewer. You will write the code in a real-time, collaborative editor or on a whiteboard , and have 30 to 45 minutes to solve the problem. This is where the real fun begins!
Your interviewer will be looking to see that you meet the requirements of the role. It is up to you to show them that you have the skills. Initially, it may feel weird to talk while you code, as most programmers do not make a habit of explaining out loud their thoughts while they are typing code.
However, it is hard for the interviewer to know what you are thinking by just looking at your code. If you communicate your approach to the interviewer even before you start to code, you can validate your approach with them. This way, the two of you can agree on an acceptable approach.
Preparing for a remote interview
For phone screens and remote interviews, have a paper and pen or pencil to jot down any notes or diagrams. If you are given a question about trees and graphs, it usually helps if you draw examples of the data structure.
Use earphones. Make sure you are in a quiet environment. You do not want to be holding a phone in one hand and typing with the other. Try to avoid using speakers. If the feedback is bad, communication is made harder. Having to repeat yourself will just result in the loss of valuable time.
What to do when you get the question

Research About The Company
When we go for an interview, most people research about the job role and responsibilities. But, no one researches about the company. Researching about the company helps to get an idea about the works and projects done till the date. It also helps to get a brief idea about the jobs and skills required for the company. And more than that, it builds your confidence levels and feels quite confident while attending the coding interview. When we are clear about all these things, it is simple to crack the coding round and impress the interviewer easily.
When we have a complete understanding of the second tip of the article, let’s understand the next tip in the article, “tips to crack a coding interview.”
How To Crack The Coding Interview With Practicing Only 30 Questions
As we always suggested in our previous posts, its extremely helpful to practice with coding questions when preparing an interview. Basically you can start with some very general questions from books like Cracking the Coding Interview or Website LeetCode. And then when it gets close to your interview date, questions from past interviews of your target company will be more helpful.
But people may wonder how many questions do I need to prepare? What is the most efficient way to practice with each question? Obviously memorizing answers to those questions will never work and over the past I saw many people practicing in highly inefficient ways that could only make them feel as if they were improving.
Quality is always better than quantity. If you can take full advantages of each question you prepared, you dont need to practice with hundreds of questions in order to crack the coding interview. In that spirit, Ill give you the most practical tips and hacks now:

The Importance Of Negotiation
Negotiation can be an uncomfortable conversation, but avoiding it altogether is a disservice to your skills. If youre able to overcome the discomfort that comes with negotiating, one conversation can earn you real value in minutes. According to Gayle, theres nothing to lose. Since its a complex conversation, its easiest to discuss with your recruiter via phone, but its ok to use email if needed. But dont stress too much about the medium youre usingjust make sure you have the conversation!
When determining how much to ask for, put a price tag on the discomfort of the conversation. Start by asking for their offer, plus a little extra. If youre not sure what to target, ask for comparables from friends. Just remember: anything additional you get from that conversation is more than you started with. And dont worry about employers rescinding offers because you chose to negotiate. So long as you stay professional, the worst they can do is say no to your ask.

Think Carefully About Languages
And when it comes to languages: try not to cling to one language alone. Instead, plan to go into the interview focusing on one or two languages that you already know well. For backup, plan to have a few other familiar options in your back pocket. The language you master does matter to some degree .
But instead of focusing only on what you already know, in the interview, its important to stress that you can continue to learn more languages over time. Dont identify yourself by the language youre most familiar withlike calling yourself a Java engineer. If theres a gap in your language proficiencies, make it clear that, given a month, you should be able to add any language to your arsenal.

Tip #: For Interviewers Distribute Your Hints Thoughtfully
For interviewers, its tricky to decide when to give a hintand when to hold back. The goal is to make sure that you have the right type of question to ease that tension.
When youre choosing interview questions, try to choose questions that have different hidden levels in them. That makes it easier to transition from one step to the next. That way, its easier to give the candidate hints when they’re stuck. Just remember: youre trying to assess the best version of the candidate. If they get thrown off, its unlikely that youll get to see the full extent of their skill setso be patient.
Gayle has a few go-to interview questions that she suggests. One of her favorites?:
Given two strings A & B, find how many permutations of B exist in A as a contiguous sequence
The reasoning: theres a simple, naive brute-force solution to this problem. But theres also another level that involves some level of hashing. If you help guide the candidate effectively, you can learn a lot about their skill set based on how they answer the question.
Rounds In An Interview:
In a technical interview, the interviewer makes an evaluation of the following:
- What does it take to become a great product manager and great leader?
- How can you reliably ship products that make a difference in the world?
- How do you build your product intuition, hone your execution, strengthen your leadership, and develop your strategic skills?
- What does it take to lead and inspire teams?
- When is people management the right career move?
- How does excellence in those skills translate into career success?

Advice With Cracking The Coding Interview
Hey all! Rising Sophomore.
Recently started studying from CTCI to get ahead and improve my technical interviewing skills. I’m not taking Data Structures/Algorithms until this upcoming semester, and found it pretty difficult to follow along with the book. It’s not that I haven’t looked at other resources to learn the material before I attempt to solve the problems, but rather I’m not sure how to go about solving them. Often times I’m stuck between implementing the data structures that CTCI talks about by myself and coding the questions out on paper. I’ll also arrive to a certain solution, only to find out that CTCI book implements it in a different way, leaving me no idea of whether my solution would be considered acceptable or not.
I’m basically looking for some tips on how to use the CTCI book efficiently, especially before the stress of the upcoming semester begins to add to my workflow. Thank you so much!

Getting Prepared For A Negotiation
Overall, make sure you’re prepared for the discussionand be ready to talk about the compensation you expect for the role. Look up comparables online through resources like Glassdoor or Levels.fyi, but take them with a grain of salt. Published salaries arent always aligned with what people are getting, since some calculate salaries differently than you may, depending on the unique components that make up their compensation. The best way to gauge an appropriate salary is once again to ask your friends in similar roles. It can be uncomfortable, but if you admit its awkward, and explain your reason for asking, most friends are willing to share.
Its also important to know that in New York, California, and many other states in the US, law prohibits employers from asking about your salary history. And if you ask for a salary range for the role, theyre required to provide you with that information. Understand your state law and know your rights going into the conversation.
