APEX Expert Solutions interview questions

Had an interview with the Head of Software Engineering. The questions mainly focused on hypothetical situations and what I would do to solve those problems. I thought the interview went really well. Afterwards I was told that I would be receiving an offer from them shortly (they even asked for my address to put on the offer letter), but I never received it. I messaged my interviewer on multiple occasions asking if there was an issue, or if something was wrong and was completely ignored. Not even a courtesy e-mail saying that they were going in a different direction. A couple of weeks later I saw the same job re-posted on the same site it had been on originally. I sent another message, as well as re-applied for the position, but once again received no response.

First interview was an hour long, and was your basic introductory interview. The interviewer asked me about myself and told me a lot about the position and the company. The second interview was a "technical" interview, but more like "given this real world scenario how would you solve it using big data". Because I have never worked with big data, I didn't really feel qualified for the job, but honestly the more I heard about the company the more interested I became. It sounds like a great job and a great company. Even though I didn't get the position, I'd still say it was a good experience. Everyone I spoke with was very nice.
