The recruiter from Optum approached me for an engg. manager opportunity. The recruiter tried to act smart as if he knows everything in tech, but he was blabbering something. He arranged for a telephone screen. Upon clearing, they asked me to come for F2F two times for about 4 technical rounds of interview.

I spoke to 2 of their architects and 2 engineering managers. All the questions were very basic and I think they asked questions on DS just for fancy. Architects lacked basic knowledge and engineering managers were rude. Based on my discussion, the technical panel looked like they are struck with old school thoughts, but they just talk about microservices

Overall, the interview process looked like the one conducted for an entry level programmer. The design round with another architect was a joke who did not understand basics of transactions and argued for the heck of it.
