Question 1
Describe the most challenging task you recently had
I applied through an employee referral. The process took 4 weeks. I interviewed at EPAM Systems (Warschau, Mazovië) in Feb 2022
Interview
Whole interview process took 1 month. There were 3 steps:
1. Interview with HR (expectations, salary, work permit, availability etc.)
2. Technical interview.
3. Interview with the manager (soft skills, salary negotiation, why EPAM)
Overall, it was good, but I got feedback a little bit late (probably because of current situation in Ukraine). Even, I called the HR a few times in order to get the status update.
