The process consisted of 5 interviews. 1 - HR call, to know about you and your experience. For me it was in Spanish since i'm Argentinian. 2 - English level interview 3 - Technical interview: Since I speak English fluently the interview was in English with an expert in .NET from Ukraine. It took almost 1 hour and 30 min and it was about answering to a list of questions mainly about .NET but also about other frameworks. Expect some tricky questions here. 4 - Project Interview: At this point I had to sign an NDA, then I met with 3 guys from Ukraine that were working for a client in New York. They wanted to know about my previous experiences and they also shared with me some information about the project and position. 5 - Client Interview: So far so good, well, here was the problem for me. Before arranging the meeting with the client I was asked to prepare a new CV following DataArt's format, 4 pages of CV writing about my last projects. Nevermind, the client agreed to meet me and previous to that DataArt made me an offer that it was going to become valid if everything went good. Finally I had the interview with the IT team (2) of this client based in NY and one guy of DataArt that introduced me to them. This interview was like coming back to step 3, they made me a lot of technical questions and dig into one project up to the point of demanding to know the magic behind the product. I tried to do my best despite the fact I felt uncomfortable during that hour. After this I waited for a response, did not have any notice the other day, they day after I asked to the guy from the project and he told me "Don't know if the HRs reached out to you already, but unfortunately the client said no". Neither I had a response from HR that day. After not responding my emails I had to skype HR and they told me the same (no explanation or reason) and that they were going to share my profile with other clients and reach back to me with news. 2 months have passed since then and fortunately I got a much better offer and I'm relocating to the Netherlands (bad things happen for a good reason) but at that moment I felt too much disappointed and after so much effort I expected at least an email. It's a pity but I wouldn't recommend DataArt to my colleagues.
