Application
I applied through a recruiter. The process took 1 week. I interviewed at EPAM Systems (San Francisco, CA) in Jan 2019
Interview
Contacted by a recruiter through Linkedin, After interview was informed its positive result, asked me join on receipt on H1b transfer receipt and also told the SOW was expired so its risky to join on receipt. Felt like total waste of time, if SOW is expired for client there is no point in conducting interview for the role.
