So the whole process basically starts with resume shortlisting, then there's an online test. After that, there's a Codepair round and then 3 virtual 1:1 interviews all on the same day. The Codepair and virtual 1:1 rounds were usually about 45-60 minutes long. Since I have about 2+ years of experience, there was also one more round with a senior person from the org, which involved some informal discussions and questions about my past experiences. That round was about 30 minutes.

- Tell me about your past experiences and answer some technical questions on DS Algo/Problem Solving in a Codepair round, where you need to implement and run the solution.
- We asked one technical question and its extension.
- Let's discuss your past experience and then tackle a somewhat real-world open-ended problem-solving question to see your thought process and how we can optimize it.

Coding Technical Behavioral
Applied through Stackoverflow. Round 1 was a 2 hour Hackerrank test. Round 2 was a 1 hour Codepair interview with the Engineering Manager. Round 3 was a 2 hour Codepair interview with 2 Senior Software Engineers. Round 4 was a 1 hour Values Interview with the Head of Engineering. I thought it went well, but didn't get an offer. The HR said I was a bit slow on one problem and didn't explain my work enough, even though they didn't ask me to. So, pay attention to everything, it all counts.

Coding Technical System Design Behavioral
I had a Hackerrank challenge that took 90 mins, followed by a brief recruiter call about next steps. Then there was a 1 hour live coding pair round. After that, there was a 2 hour round covering algorithms, system design, and competency. The whole process could be improved. After the live pair coding, the recruiter told me I was good for the next round. But then, for over a week, the recruiter didn't respond about next steps or schedule calls. They also didn't reply to my 3-4 follow-up emails. After more than a week, the recruiter scheduled another round (just to schedule it, I guess) which I felt went okay. Immediately, within hours, I got a rejection email. My advice to the recruitment team: Don't waste time. If you find a better candidate, just say so. Don't schedule rounds unnecessarily. Communicate better. Don't disappear for over a week without replying to follow-ups.
Confirmed questions7 questions
- For the Hackerrank challenge, the question was about prefix expression.
- In the live coding round, we had to find the co-occurrence of words.
- For the algorithms and competency round, I was asked to find and fix bugs in a code.
