Optum Senior Software Engineer interview questions

It went good and has technical, managerial and HR rounds like other companies do. Complexity level is moderate. As per the technology experience and requirements for the role questions will be asked.

Technical Interview - Recruiter/HR scheduled a meeting with the tech interviewers but did not include me, just called out of the blue and the tech interviewers were already in the call. Final Interview - a late-night schedule that was cancelled last minute, like 4 minutes before the scheduled time. Inquired for the reason of cancellation - no reply until now.
