Two stage interview process. First round conversational and second round required me to put together a presentation on an acquisition in the market. I put a lot of effort into the presentation and the least they could have done was inform me I had been unsuccessful in my interview. Several follow up emails etc and not even a response to say no. It’s now been over 5 months since the interview. If that’s how they treat people then I’m actually glad they never made me an offer.
