I applied online, this was followed by a phone interview a few days after the application after which I was invited for an in-person interview. I was introduced to members of the Big Data Systems team and the questions mainly revolved around my experience with projects at and outside of university, my knowledge about the company and a few technical questions. I was told by the main person interviewing me that they would get back to me by the end of the following week with their decision (negative or positive), as that person was going away on holidays for the first half of the week after I had my interview, but I was never informed of any decision. Do not tell your candidates that you will contact them if you intend to not contact them at all. Instead be open from the beginning and let the candidates know that you will only contact successful candidates.
