I applied through a recruiter. The process took 4 weeks. I interviewed at Optum (Bombaim) in Feb 2021
Interview
I don't think they're interested in interviewing anyone.
Went through a 3 hour long coding test, they call it Codality.
The interview coordinator tried to schedule a few times, but ultimately got it scheduled almost a month after the test happened (I guess they already got their desired candidate by then through whatever mode).
During meeting, stayed for quite a while, even emailed the scheduler & other Optum participants in the meeting, but there is absolute silence.
Had to call the interview coordinator to report the issue.
I applied through a staffing agency. The process took 2 days. I interviewed at Optum (Chennai) in Oct 2020
Interview
Code test with 5 questions from HackerRank. 3 of them are from DS and Algo and 2 are SQLs
2 one to one interviews with senior engineers on coding skills and design skills
I applied through a recruiter. The process took 2 weeks. I interviewed at Optum (Bengaluru) in Sep 2017
Interview
The recruiter called and informed that a selected few are invited for the interview. When I reached there, I was shocked to see the number of people who were in that building. It felt like a walk-in, though it was not.
There were 3 rounds. First-round focused on general stuff. The second round was some programming questions and the third round was mostly system design.
