2nd Interview round was very difficult. I was asked to code a question. I coded in recursively and then I was asked to do it in iterative way. The question was new and there was not even a bit of help from interviewer.
1. Give a number k, output how many prime numbers between 2 and k (inclusive) 2. Give two strings a and b, tell whether b is a sub sequence of a (not substring), using recursion first, then using loops, then tell which one is better. 3. If a database query manager buffer is filled without any more space, what kick-out mechanisms would you use? FIFO, Oldest, Least Recently Used etc. Why?
Actually, the questions are not hard. For example, binary search, validate parentheses, find the kth element, etc.
All problem had some tricks but be calm as they are looking for problem solving approach..
none
The third question is a bit unexpected. I was spending a lot of time thinking how to write this efficiently, but didn't finish it. I should just write a straight forward one, and try to improve it later.
Write a method to reverse an arbitrary integer. Then find all the cases to test it.
Technical questions are very difficult, but if you are well prepared on the requirement of the job position you will answer to most of them. Programming excersice are very difficul and challenging.
Tell me about a project you have worked on and any problems you faced
