Overall, there were 3 technical rounds: 1 Telephonic and 2 F2F rounds.

The Telephonic round was pretty good. It covered most of Swift programming and iOS-related questions, along with some logical questions.

I had two F2F rounds at the Grab office:

1. The first one was mostly about basic programming. They focused mainly on Data Structures and Algorithms. I answered the first question with multiple solutions which could have been done very simply, but I overthought it. The interviewers were experienced and patient.

2. This round was mainly about iOS-related problems. The person who took the interview was almost of my experience level. They kept asking multiple implementation problems with respect to iOS. The interviewer wanted to make sure that they knew better than me. I did not answer 2 questions properly as I was frustrated and lost interest due to the behavior (closing eyes and not listening respectfully).

Respect other professionals who come for the interview.

Suggestion to the interviewer: I have taken 100+ interviews in my career and have learned from my past experience. People come seeking a job, not "begging" for it. Respect others' opinions and try to see how a person approaches a solution for any given problem, not to prove that you know better!

1. Within a given timeline, find the approximate number of cabs that would be required with respect to an approximate number of riders. Given timeline: 12 AM - 12 PM Find the approximate number of cabs required.

2. Given a binary tree, print its left view.

3. UITableView with image downloading, caching, etc. Unit test cases, concurrent programming, etc.
