The test was on Codility and had 3 questions. Don't remember them exactly but they were on Arrays, String manipulation, Graphs. Solved 2.5 questions and was invited for the interview.
Round 1: Design Round
- How to migrate a database without facing downtime
- API and Database design for Lottery system with defined probabilities for certain denominations.
Felt like this round went pretty well. The only feedback the interviewer gave was to be confident in my choices and not get confused.
Round 2: DSA
This round was taken by an Indonesian interviewer whose English was not that great. Since I knew a bit of Indonesian I talked to him about Indonesia in their language (Kind of got carried away and wasted time here). He said he'll be asking 2 questions in this round.
- It was a Graph based question which can be solved with some modifications to DFS. But more than that the taking input was complicated and implementing it took a lot of time.
The problem with the interviewer was he doesn't know how to solve the question. I was actively trying to discuss my idea with him. He never paticipated in the discussion. He was like just take the input and give output. If you are done with that then I'll give the next question.
I did solve it though but 48 minutes in the interview were completed. He said there's not time for another question let' wrap this up.
From all the Grab posts I've read almost everyone solved 2 DSA question. Maybe solving only 1 question led to my rejection.
