Technical
It was a technical interview and I had to take a technical assessment. I was given a codebase and navigating it made me lose my composure. It was a great experience though.

Coding System Design
My interview process was: first round was an assessment, second round was a machine coding challenge where they reviewed the system and used the STAR method, and the third round was system design where I had to design Google Sheets from a frontend perspective. Unfortunately, I was rejected after the system design round.

Coding Technical
I applied online. After a few days, got an email from the recruiter that profile was shortlisted and they'd like me to take a HackerRank test. The test had three questions: 1 problem solving and 2 small react projects. I finished it. Next day, the recruiter emailed saying I passed the test and they want to move forward, asking me to schedule interview slots. However, they stopped responding. I tried contacting the recruiter on LinkedIn, they saw my profile but ignored my message. Getting selected or rejected is one thing, but they should at least update candidates. I spent 2 hours on the test, and the company couldn't even send an email or call to explain. I'm not sure what happened. It was a really bad experience. I hope they don't treat other candidates this way.
