I got a call interview for UAT tester but they said they changed their mind and they needed a developer. So they ask me can I work as a developer? Then they said that I should wait for HR email. After 1 week they send an thank you email and I failed that interview

Applied through an institute, process took in a day. They said to come at 9 but started at 12.30. Initial round was jam followed by an aptitude round which includes math, verbal and essay writing. After that technical round fourth and final was hr interview held at csc hyderabad premises. They said 4500 salary per month with 2 years bond should relocate. Results are not yet announced. I have wasted my whole day
