I got to the first interview stage fairly quickly - within one week of applying. While they told me roughly when the interview will be (a couple days' window), the exact time of the interview was informed to me less than 24 hours before. The interviewer was nice and I think I could correctly solve all the questions (maybe not as fastly and efficiently as they expected). After two weeks of the interview, I wrote to them asking for an update but there was no response. It has been over a month since the interview but still no update. If a candidate is rejected, I think he/she deserves the courtesy of being informed about it.

First interview with HR, it was asked questions about statistics that made sense for the role. They validate the salary expectation and described the benefits (very good). Second interview, Straightforward with their needs for the position. Good conversation with the manager, the guy was sympathetic.
