Had interview rounds after getting a referral + technical online test. Appeared for 3 rounds - 2 Technical + 1 HR. Technical rounds tested your ability in Python, ML, GenAI and previous projects. Came to know in the 3rd round that they won't be able to match salary demands even though I shared the same before the start of the interview process itself. I got ghosted after this. Absolute waste of my time and effort.
