Interview Preparation Tips
- Don't waste your time on this company
Despite giving so many rounds of interview (on multiple days), there was no offer given.
After asking the external HR again (after a month) about why there was nothing yet, I was told that the position no longer exists.
This speaks volumes about the company's ethics.
My advice: Avoid wasting your time with this company. They don't have the basic courtesy to even let a candidate know why there's no progress on his/her profile. You are better off going after companies which actually give offer letters soon.
