Optum Senior Software Developer interview questions

Intro call from recruiter. One hour interview virtual. List of people that showed up was totally different then what was indicated on calendar invite. Went through experience. They all said they used to be a business analyst. Ghosted after interview.

I went through only one round of interview. It was of 1 hr. Your techstack questions are asked in detail with edge cases. Then Javascript was asked for last 15 minutes. The interview went pretty well. But along with my tech skills, they are looking for typescript expert as well as jest expert.
