I applied online. The process took 3 weeks. I interviewed at Grab (Singapore) in Oct 2020
Interview
Hiring process included 1 code quiz & 3 rounds of 1:1 interviews.
Online round: Code test on Codility. 1 hour 30 mins for 3 questions. I found the questions to be of Leetcode easy-medium difficulty, and managed to score 100%.
Round 1 (backend, 1 hour): Starts off with easy questions which get increasingly difficult. Pseudo code is sufficient; I just needed to explain the code without executing them. Ended with a system-design question - "how would you design a room booking system?"
Round 2 (frontend, 1 hour): Oddly, I got received the same question as the previous round. I raised this to the interviewer but we still proceeded. I just needed to explain my approach without coding. Bulk of the interview was coding a JS event listener using OOP approach.
Round 3 (hiring manager): Was supposed to be culture fit and systems design but it ended up just being culture fit interview with 0 technical questions.
Overall, all interviewers were pleasant and I had a great experience interacting with them, esp the hiring manager. Recruiter was extremely helpful and quick to respond too.
Interview questions [1]
Question 1
Easy-medium difficulty Leetcode questions. E.g. valid parentheses
Get messaged by HR via LinkedIn, schedule the interview for the next day, and interview with the user the next day after the HR interview. Overall, the HR and user were very kind and accommodating.
I applied online. The process took 4 weeks. I interviewed at Grab in Jun 2021
Interview
1st Round: 3 Leetcode questions, 1 easy and 2 medium level difficulty. Optimization is important as it impacts your overall score which you get after completing the questions. I got 81% and moved on to the next round
2nd & 3rd Round: Two interviews back to back first one was about frontend and the second one was about backend. Interviewers were very friendly, felt like I was at a mamak and chatting. Mostly basic stuff for CSS and JS, expected way harder things but the easy stuff that I haven't used in awhile came out. For the backend portion it was mostly about my projects and how I scaled them, I work more with ML so I talked about those a lot.
Interview questions [1]
Question 1
Frontend coding question was about taking user input and converting it to a bar chart based on percentages. Backend coding interview was about validParentheses question on Leetcode.
First phone interview. Then after that they will do a series of interviews for frontend and backend. Then after that they will send a feedback regarding the interview if you failed or passed.
