Interview took about 2 weeks to complete. There were three rounds of interview. All three rounds went really well as I was able to answer the technical puzzles asked and interviewers seemed convinced as well. Interviewers were very friendly and clarified the problem statements whenever required.
What was good
Interviewers were very friendly and had insightful discussion.
What was not good
-
No interview feedback given. So, basically you have no idea what you did well, what you didnt do well. You need to push the HR to get back the results whether you are moved to next round or not.
-
Interviewers didn't show up in the meeting and wasted entire day (happened for one of the round). I had to push HR to get back on the update.
-
In any interviews, if you are performing well, you're most likely getting selected. But Redbus HR is not responded back why I was rejected despite of performing exceptionally well on three rounds of technical interviews. It's just disappointing.
After three rounds, this is the HR response:
"Your candidature is on hold as of now. We are evaluating some more candidates. I can give you an update by this weekend."
And then absolutely ghosted after that!!
They shouldn't be wasting time if another candidate is already hired. I'm just curious whats the passing criteria if interview performance is not the first priority!
Interview Questions
- Asked about recent projects
- URL shortner system design
- Questions on scaling the system to meet the demands.
- Very basic DSA question on array: check if the array is already sorted or not!! Yes, you heard it right!
- Questions on live chat app design, how to scale them, communication between different microservices
- Questions on websocketing, message brokers, database design, choosing relational/non-relational databases, gRPC vs REST, which one to chose under a given scenario, concurrency handling in high traffic booking site etc. None of them were that challenging.
In a nutshell, Redbus is not a bad company to join, but be mindful about the experience that I shared above and plan accordingly!
