Telephonic Interview - 2 interviewers - 2 basic algo questions on strings. I answered both the questions in time. They wanted me to do better on time complexity on 2nd question, mine was O(n) time and O(1) space, since I had insertion of data in my hands. Then I spoke out the better way, half way coded it but there was no time to code it fully. According to me, I did really well. These guys are totally unpredictable and naive. 2 freshers test any level of experienced guys. They just have 1 solution in mind. You do it the other way, you are not getting it. They expect you to do 2 questions completely in the best ways (acc to them), at the same time it should be readable, maintenable, logical etc - everything.
