Total 4 technical rounds. Got rejected at second round. For the first round, I got a lc medium question with two pointer. For the second round, two lc medium questions, one is the in-space reverse string and another is recursive traceback. I failed to solve the in-space reverse string (coz honestly I didn't practice this question before, dunno need to reverse the whole string first), so I got rejected. Two interviewers are all very friendly. The first one is an indian based in singapore, and he's generous with giving hints. The second one is a chinese based in singapore, he's nice too, but didn't willing to guide me.
