DTCC Software Engineering Manager interview questions

Applied online. Recruiter reached out after 2 weeks and did initial phone screening. A followup call with Hiring Manager was setup in a week's time. After 10 days, I received an email addressed with different candidate name requesting Skype meeting for next level of interview. When I asked if the email was sent in error, the candidate coordinator stated that it was an error on his part and the email was intended for me. 2 days before the actual Skype meeting, I received a notification that they decided to proceed with another candidate.
