Total waste of time! Don't even bother entertaining these folks for an interview. They took 4 interviews, 2 virtual and 2 face to face over a span of 2 months. Then they just ghosted for v. long duration, and after following up multiple times, got a message from the 3rd party recruitment firm guy, that they rejected due to lack of exposure to some technology. Wait what? I precisely mentioned my tech skills in my resume. And it took them 4 rounds of discussion to identify that, this shows the inefficiencies these folks have. So save some time for yourself.
