Had a very weird experience with Grab. Firstly, there was a DSA round, where my performance was average. They said I didn't clear it, so I was fine. Then, HR contacted again, saying that they would go through further rounds. All rounds went well. I got 1 weak Yes and 2 strong Yes. At last, I was rejected because of R1. Wasted my 2 weeks at least. Very bad experience. The interviewers had not even gone through my resume before the interview.

There were 4 rounds: R0- Competitive level coding assessment on Codility. R1- Easy to medium Leetcode questions on DSA. R2- Low-level design of Jira ticketing system. R3- Basic questions on system design, my experience, low-level design of Logger. Hiring manager round: Questions on my work experience.
