1st Round : (On-campus online test) There were 39 MCQ questions based on code snippets and OS questions, 1 Coding question - Zigzag Manner in string. Verdict - Selected 2nd Round : (On-campus technical) Not gonna lie ! Interviewer was experienced and relaxed, gave 1 coding question on leetcode(easy), asked me to write and explain any sorting technique, I explained Merge sort. Then he told me to write a query. And later he asked some random DSA theory based questions and from oops too. Verdict - Selected 3 Round - (In Company technical) this time interviewer was most unknowledgeable and a clueless person I have ever seen in my life. He asked me to find a duplicates in a array. I gave the approach where, first I'll sort the array then iterate over it and check the duplicate using if else condition. He said don't use any inbuilt function. Then I said let me do it using merge sort. He told no sorting techniques! Then I implemented a dictionary and solved it. He wasn't satisfied ! Then again I used a different technique using inbuilt function in python that is set(). He said this approach is good but set() is not inbuilt function. Actually he had 0 knowledge in python that was the issue. Verdict - Some random lady came, and told me that I'm not selected.
