Horrible! Worst interview experience in my entire career so far. Why waste the time of candidates if you don't care to communicate the interview process and results appropriately.
After going through several rounds of interviews and waiting for over 6-8 weeks, I never received any reply to the several emails I sent requesting about the result. The recruiter ghosted on me! It clearly shows their lack of professionalism and poor company culture. These companies are rated tier 3 or below for a reason, STAY AWAY!
