I had applied here at Apostek through Elitmus in Sept 2018 and was shortlisted for Round 2 which is an online coding round where questions are asked like one was on graph traversal to find the height of the tree, another was Mafia family problem where he wants to know the minimum number of members in the family of the opposition, other was a problem where we have to find the minimum height of the flower from any array of flowers which was given special water, thus increasing the height by 1 unit everytime. Mostly if u clear 2/4 test cases ,u will called for interview event at the company in Bangalore. Only 10-15 student were called for interview process, (i was with them obviously) Initially we were given Presentation on Apostek . In first round, Interviewee asked me questions from OOPs concepts(polymorphism, inheritance etc). WAP to check a number is palindrome or not. Stack and queue basics. WAP to get distinct elements from array with duplicates. After that selected students were told to wait for next round. In Second round, Interviewee told me to write code for inheritance and polymorphism and asked few questions related to those concepts . Difference between Set and list, Array and linkedlist, Set and Map. WAP to return duplicates value from the array. One more Round was there for me where he asked me some puzzles and asked to code for stack, queues and linked-list considering all possible outcomes. I coded as i was asked and i got selected with two others. They offered me a job which i joined later. They sometimes take additional rounds to check the capability of the candidate else generally its 2-3 rounds.
