J'ai postulé via un recruteur. Le processus a pris 1 semaine. J'ai passé un entretien chez EPAM Systems (San Francisco, CA) en janv. 2019
Entretien
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.
