Very worst HRs, I received a call after interview we were negotiating salary and HR said she will check and call back, 1 day I waited but no call. Then I called HR she told I'm sorry we cannot provide that salary, then I asked to explain the salary what they're willing to offer. HR said she will go to her desktop and call me it's been 20 days still I didn't get a call back from her, I tried calling but no response, I wrote an email no response.

Worst wipro HR service.
