I was rejected after the first interview then I was called back because a new similar position opened up I was given just one day notice for the interview which went well. After this second interview the Hiring Manager told me they hadn't taken a decision yet. However, the recruiter had already sent me the rejection email. I just wasted my time they probably just needed to fill the pipeline.

Internship process: first you join a one to one interview which are for competency based questions then you will be asked to join an assessment centre which consisted of giving a presentation and working in a team to solve a problem.
