How I Got Here
I started programming in middle school, but when it came time for college I pursued a degree in Economics. My rationale was that there would be too many programmers looking for jobs by the time I graduated. Boy, I was wrong.
Later, I joined the Army to become a programmer, but the recruiter talked me into a military intelligence position, and I spent the next two years studying the Korean language. I served in South Korea for 2 years afterward.
Before I left the Army, I attempted to get back into programming and was surprised at the difficulty. I had learned BASIC in middle school and kept programming it through high school. But I restarted my programming studies with C++, and the leap was too large. I just couldnt grasp it.
I did enjoy making websites, however, but I used software with a Word-like interface that I used to publish my websites. I didnt know how to make websites from scratch.
After a year of intense study, I landed a job in the Seattle area, and Ive been here ever since.
Ive been a web developer now for 15 years. Ive started 3 companies, 2 of which are still running and generating revenue. Ive worked at large and small companies, helped startups launch and grow, and recruited and managed teams. Ive been a product manager, a CEO, a designer, and a marketer.
What’s The Best Way To Prepare For A Coding Interview
Data structures and algorithms will likely be an integral component of the coding challenges, so it’s important to spend time on those topics when preparing for your interview. Try to mimic the actual interview conditions in your prep: Practice on a whiteboard and set a timer to emulate the time pressure during coding challenges. As you write your code, practice explaining your thought processes out loud.
It’s also key to do your research on the company this will give you a better idea of what languages, frameworks, and other tech it uses. You can also research the company’s current strategies and goals to best identify and articulate how you will contribute to the company.
As the interview processes for many well-known companies are widely discussed, this research could lead you to specific information about your upcoming coding interview. At Google, for instance, applicants must pass a pre-screen and an onsite interview, which includes meeting with 4-6 Google employees for nearly an hour each.
Remember that while much of the interview will focus on technical skills, there will also be behavioral and soft skill components involved. It’s a good idea to connect to the company’s recruiter to get the full picture of the process.
Lastly, run through a couple of mock interviews. Have a friend play the role of the interviewer or use free mock interview sites like Pramp to practice.
Software Testing : Get Started With Software Testing Types
As software becomes more advanced, software testing must evolve with it. Software testing is how we check if the actual software product matches requirements and runs properly once distributed.
Today, well look at these modern methodologies and how they lead to more polished software products.

Practice Is The Only Way You’ll Get Better
You have to create and stick to your practice schedule. Diligently. It’s surprisingly difficult to stick to simple habits, but that’s often the difference between success and failure. For example., 2-4 hours a day to solve one or two problems is a great habit â necessary and often sufficient. But it’s imperative that you actually do so several days a week for a number of weeks, rain or shine, in order to get cumulative benefits.
How You Can Stand Out From Others And Pass Every Time
Is there anything more intimidating than live coding in front of someone during an interview? I think not.
I used to be so frightened of live coding interviews. So much so that, for a while, thats what prevented me from finding a new job. I didnt want to have to study complex algorithms and computer science riddles that nobody uses in their day-to-day job just to land a new role.
This just didnt feel like an efficient use of my time when I could be grinding away at real-world projects instead.
Eventually, I bit the bullet and started applying for new roles, knowing very well that the coding interviews could not be avoided. Practicing SQL Leetcode problems each day definitely did help, but theres so much more to them than knowing the language.
At the time, I didnt quite realize what makes one candidate stand out from another in a coding interview. Now, I perform them at my current company and see a huge difference in the candidates I pass and those that dont make it to the next round.
Heres how you can pass your coding interviews:

The Google Onsite Interview
The Google onsite round involves speaking to a number of Googlers. Usually this will include four to six separate interviews, including one lunch interview.
Generally, you will be asked primarily coding interview questions and potentially one or two system design questions as well.
The more experience you have, the higher proportion of system design and topic-specific questions you can expect to be asked. Google rarely asks any system design questions to engineers with less than 5 years of experience.
Each interviewer collects feedback on how well you performed during the one-on-one interview with you. This feedback is collected by each interviewer independently as to eliminate cross-chatter and biases between your interviewers. If you felt as if you performed subpar in one of the interviews, that baggage stays there and does not follow you into the next interview.
Practice Like You Play
Effective practice is realistic practice.
In the midst of an interview, you want to be focused and able to spend the majority of your mental energy on the problem given from the interviewer. You dont want to be thrown off by extraneous factors such as not being used to writing code in a non-IDE environment.
Here is a list of factors that you should be mindful of when developing your practice regimen.
The phone interview is 30-45 minutes, and each of the one-on-one onsite interviews will be roughly 45 minutes to an hour each. In each of these scenarios, you will be presented with at least one question, which, in most cases, is a coding category question.
In order to effectively practice under time constraints, one strategy would be to select one specific problem.
For instance, selecting a problem from one of the book or video resources under the Additional Resources section of this post would be a good place to start. Then, start a timer and attempt to solve the problem without access to an IDE.
Following this practice for a few different categories of questions will give you some signal with respect to how you are faring with time constraints. Getting optimal solutions within the time interval of 30-45 minutes consistently for problems of varying difficulty is the ultimate goal. If you are struggling to hit this goal, use this as an opportunity to tighten up this area is something you will need to work on.

Overview Of Google Interviews
The whole interview process takes 2 to 2.5 months to complete. Google interviews for software developers consist of 5 to 7 interviews in total. This includes an initial phone screen with a Google recruiter, followed by 4 to 6 on-site interviews with different Google employees. All coding challenges are done on a whiteboard, Google Docs, or a Chromebook.
Google normally hires at level T3 with T11 being the height of levels. T3 is an entry-level, full-time software engineer with an undergraduate or Masters degree. The average salary for a T3 employee is $117,000 annually. Google prefers the following programming languages: Java, C++, C Go, and Python.
There are three types of coding problems you can expect to see in a Google interview.
System design questions: these questions gauge your ability to handle high-level system design with scalability in mind.
General analysis questions: these questions gauge your thought process through mathematical or opinion-based questions
Test Case Closure And Analysis
This step is about recovering solid, reportable takeaways from the tests. Most companies will have you write either a daily or weekly report that summarizes how each test went and what changes will be made as a result of the test.
From here you can either:
- Tweek the test and repeat for more information .
- Return to develop solutions for the product using the test results
Using agile testing practices, youll complete this test cycle before you create the product code as well as after. This allows you to speed up development as you keep the test specifications in mind during product development.

What Is Software Testing
Software testing is a cyclical process used by developers to continually evaluate and correct the functionality of the features during the development process. Software testing compares the current build of the software with software requirements to confirm there are no missing requirements.
It also verifies that software can function correctly across different mediums or with existing integrated software.
Without software testing during development, youd only know if your software worked when it reached the end-user!
Data Structures And Algorithms
Impact: very highFrequency: very high
If you dont know what data structures are, then you need to build a strong foundation in computer science first before you are ready for the next steps.
In other words, if you are not familiar with terms like linked lists, trees, graphs, binary search, and dynamic programming , then you have some work to do!
A solid understanding of data structures and algorithms help you write efficient programs that can run faster and utilize resources more efficiently.
It is one thing to write code that is functionally correct, it is a completely different thing to write efficient code that is functionally correct.
Interviewers value candidates who can analyze code, spot performance bottlenecks, and possibly come up with better solutions.

Practice With Mock Interviews
The steps mentioned above can be rehearsed over and over again until you have fully internalized them and they become second nature to you. A good way to practice is by partnering with a friend and taking turns to interview each other.
A great resource for preparing for coding interviews is interviewing.io. This platform provides free and anonymous practice interviews with Google and Facebook engineers, which can lead to real jobs and internships. By virtue of being anonymous during the interview, the inclusive interview process is unbiased and low risk. At the end of the interview, both the interviewer and interviewee can provide feedback to each other for the purpose of helping one another improve.
Doing well in mock interviews will unlock the jobs page for candidates, and allow them to book interviews with top companies like Uber, Lyft, Quora, Asana, and more. For those who are new to coding interviews, a demo interview can be viewed on this site. Note that this site requires users to sign in.
Another platform that allows you to practice coding interviews is Pramp. Where interviewing.io matches potential job seekers with seasoned coding interviewers, Pramp takes a different approach. Pramp pairs you up with another peer who is also a job seeker. The two of you take turns assuming the roles of interviewer and interviewee. Pramp also prepares questions, and provides solutions and prompts to guide the interviewee.
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.
