Overall there were 3 technical rounds 1 Telephonic and two F2F rounds. Telephonic was pretty good. Covered most of Swift programming and iOS related questions along with some logical questions. Had two F2F @Grab office. 1. First one was mostly about basic programming. They focus mainly on DS and Algo. Answered the first question with multiple solutions which could have been done very simply but I overthought about it. Interviewers were experience and patient. 2. Mainly iOS related problems. The person who took the interview was almost of my experience. Kept on asking multiple implementation problems WRT iOS. Interviewer wanted to make sure that he knows better than me. I did not answer 2 questions properly as I was frustrated and lost interest by the behaviour(Closing eyes and not at all listening respectfully). Respect other professionals who come for the interview. Suggestion to the interviewer: I have taken 100+ interviews in my carrier and some learning from my past experience ---> People comes for seeking a job and not "begging" for it. Respect others opinions. And try to see how a person approaches towards a solution for any given problem not to prove that you know better!!
