They were pretty fast. I applied some time in late January- early February and the responded within the next week. Got to the phone interview, which took about an hour. some of the questions were to design some simple algorithms, ie given a sequence of numbers, print the non-duplicated elements. they also kept asking about the time and space efficiency of the implementation and tried to have you come up with better ones.
Interview questions [1]
Question 1
Given a sequence of numbers, is it possible to recover the original tree structure of the array before it became an array using inprder traversal? what about preorder traversal?
Phone screen went very well, i passed to the onsites and they gave me the problem statement and i proposed a sub-optimal solution. They told to me come up with more optimal solution and didn't give me much time to think about it. They got impatient and gave me a hint. I figured it out and solved the problem, but apparently they thought I needed hints, which I didn't ask for.
15 minutes talking about resume, 45 minutes for 2 medium leetcode style coding questions (using code share), the interviewer was very friendly and communication is even more important than passing all test cases.
Overall, it was a positive and professional interview experience, though the interviewer was on the stricter side. Unfortunately, I was dealing with an illness and wasn't able to prepare as thoroughly as I wanted to, which left me feeling a bit off throughout the conversation. Despite not feeling my best and facing a tough interviewer, the process was well-structured.
