I had a very bad experience interviewing with Unity. The whole process took 2 months. There were four rounds in total. After the third round, I was told that they dont have budget for my expected CTC , though the recruiter agreed initially on the CTC during the first call. I got a rejection mail as well. They called me after a week and told me they are going forward with my candidature and they are ok with my expected CTC and I attended the fourth round and now I am ghosted.
