I managed to get 2 technical interviews with them for a total of 3 hours. The first one lasted 45 minutes (an hour actually) and consisted of general java knowledge questions. At the end there was a string manipulation task. The second one lasted 2 hours and had a task about a reader/writer program. After having wasted 3 hours in total, they decided not to progress further with the application. When I sent an email regarding that, so I can understand their reasoning and improve myself for the future, they never replied. I believe I dodged a bullet, seeing all the reviews here. Avoid this company.
