HCLTech Senior Linux Administrator interview questions

The interview was held on 27th November 2016, Electronic city, Bangalore. I reached the venue at 9am and the first technical(online) round was at 1pm. It almost took 30 minutes to clear the online test. I was selected for the next technical round on the same day. I finished my second technical round by 3pm. The second round went on for almost an hour. I was selected for the second round as well. The HR asked me to wait for couple of minutes. I was asked to fill the form and leave for the day. On the next day, i.e on 28th November, I received an email from an HR to submit the documents asap so that offer letter can be released. So by EOD, I shared all the documents. I waited for a week, there was no update from their end. So I sent an email to HR seeking for an update.As expected, there was no reply from her end.I was pissed off with this unprofessional behavior. I kept sending emails weekly once and never received any update from her. On Jan 11th 2017, another HR called me around 7.30pm stating that I would be receiving a call from the client tomorrow (Jan 12th at 11am) for the next technical round. I was surprised and was thinking "oh, this is not over yet, and why the hell ask for documents etc etc" The next day, Jan 12th, I was waiting for the client call and guess what, As expected none of them called.This is really heights of unprofessional-ism !!!! I sent an email to HR stating that i didn't receive any call but never got any reply from her as well. I kept sending emails seeking for an update, and till now there is no update from their end. They aren't replying nor providing an update for the selected candidates and they are still hiring for the same position. All this is just for publicity ? Do they just wanna show that they are conducting interviews. Wish I could reach out to the CEO of HCL!!! Never ever attend the interviews conducted by HCL. Cheers!!!
