I got the call from the recruiter for the position. It was for some mobile optimization team.

The overall process took 3 weeks. The first round was a telephonic round, then 5 face-to-face rounds in their office. After that, I was given a home assignment that needed to be finished in 24 hours.

After completing all these rounds, I was informed that my candidature is on hold since the requirement is on hold. It's already 2 months over, with no information on the post.
