I applied online. The process took 2 weeks. I interviewed at Helmes (Tallinn) in Nov 2017
Interview
There was a task followed by phone screening. Finally technical interview on-site.
Interviewers may trick you into questions that they even don't know answers to.
They offered entry level job to me after having 7 years of experience in software engineering. And finally becoming silent when I asked couple of questions regarding the position.
