I applied through college or university. The process took 4 weeks. I interviewed at Optum (Cool Springs, TN) in Mar 2016
Interview
Started with an interview at my university, which was fairly basic. They asked about my classes, whether I'd done any personal projects, and my familiarity with software development methodologies like agile. There was a second round interview at Optum that was a bit more technical, but ultimately it seemed to come down more to personality than technical ability. A friend with more experience and a better GPA who was further along in the CS program interviewed at the same time and didn't make it to the second round.
Interview questions [1]
Question 1
They asked me to describe experiences that exemplified the company's core values (Integrity, Compassion, Innovation, etc.)
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

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 3 weeks. I interviewed at Optum (Eden Prairie, MN) in Oct 2022
Interview
The interviewing experience for their internship, consisted of a video-recorded interview and a virtual zoom interview. Mostly behavioral questions with a few questions about past technical work on your resume. The interview was with a real engineer at the company, not an HR person.
