Aptitude test was round 1. After that around 50 students were selected for interviews. They had an HR round first, and then technical round. HR round was just a formality and sort of a hygiene check. Technical round was relatively easy and comfortable
Interview questions [1]
Question 1
Asked me to explain pseudocode for following question:
You have a string that is made of 'AM' substring. It can only be expended in 2 ways: 'AMAM', 'AAMM'. Now the 4 letter string can be expanded in 5 ways by inserting 'AM' anywhere in the string. If given a long string, how to check if it is valid and following the above rules
There was a phone screening and then a remote interview. Remote interview just asked for the basics, fundamentals of computer science, and any related experiences. It was a long friendly conversation.
I applied online. The process took 4 weeks. I interviewed at Optum in Jan 2022
Interview
A 6-question video-recorded interview about personal skills and how you approach problems followed by a technical challenge. Finally one more interview with a few technical questions. Nothing very in-depth but what is your technical background type questions.
