UnitedHealth Group Senior Developer interview questions

First round technical interview; two questions, one related to Strings, one related to dynamic programming. Second round manager interview; not technical at all, entirely about background, personality, and passions. Third round team interview; vaguely technical ("what approach would you use to solve ____?"), but mostly evaluating "team fit".

It is a three step interview. All three of my interviews were phone interviews and very simple and standard questions. The last round was a white board round with screen sharing.
