Saurav Dey's Review Sourced from Google
Waste of an organization. Wastes time on interviews. Relative had all 3 rounds and final round the interviewer told that all went well and would get back. But later the HR emailed a different statement which contradicted everything. Strange on why they waste people’s time.Seems unprofessional culture still.
Chirag Panchal's Review Sourced from Google
What are you thinking when it comes to conducting interviews? Why waste someone’s precious time? This behavior from interviewers and HR departments is really frustrating. It’s infuriating when there’s little to no response, and if someone inquires about the outcome, you simply say it was negative. On what basis are you assessing someone’s capabilities?I feel strongly—and I'm 100% sure—that I have shared everything you wanted regarding my experience. It's disappointing to see that you're just keeping a record of the interview without any real engagement. Everyone who attends interviews is spending their valuable time, and it feels like that time is being wasted.I've never encountered anything like this with a company before.I want to determine whether you are genuinely looking to hire someone or if you are simply wasting people's time. For those who are working and interviewing, how capable do you think your interviewers are? I don't see any technical knowledge; it seems like they are just pretending to know everything.I need a response from the CEO who is overseeing the situation.
