Toptal Data Scientist interview questions

I was approached on LinkedIn portal. Interview process was a Skype call, the talk consisted of couple of topics. First was introduction to the company and work culture. Secondly, we discussed the role which I applied. Finally, for most of the time, I had to describe my career history and tell little about my current and past projects. Some technical aspects were dig into as well. Company never contacted me again and I got no confirmation/rejection e-mail, therefore the negative overall experience.
