Infogain Full Stack Developer interview questions

Very disappointing experience with the HR team. After clearing all interview rounds and aligning on expectations, I was later informed by the senior HR that they couldn't match my current offer due to a "miscommunication" about the CTC. It’s unacceptable to bring this up at the final stage after investing so much time and effort. The process lacked transparency and professionalism. Worst interview experience I’ve had so far.
