I applied through a third-party advertisement, wherein they ensured a smooth and efficient application process. After about a week and a half, I was scheduled for an international phone call interview. They were late for about 30 minutes. The interviewers composed of 3 people, with a head interviewer and 2 other technical interviewers. I did not expect to be asked highly technical questions for an internship that seems to be outside the scope of the indicated job description, and not to mention that it is only supposedly a "good to have" as clearly described in the description. I couldn't answer the technical questions at all. I tried to explain that I can learn at a fast pace and independently, since I do have a desire to learn. The interview ended with some generic questions about how I work with people. The interviewer informed me that they will contact me a week after, regardless of the results and some recommendations behind why I may have not obtained the internship. Unfortunately, it's been about a month already. I know I haven't got the internship, but the least they could do is keep their word and just inform me of the results. Their integrity is at question and I find it quite unprofessional.
