Uber Software Engineer ios interview questions

I applied online and contacted by a technical recruiter. After initial phone screen I was set up to talk with the hiring manager. After that they wanted to move forward with the process and gave me an iOS project challenge to complete within 10 days. I implemented the challenge, delivered great code with comments, wrote test cases and even had time to design UX. This was 2 months ago... I haven't received ANY feedback or ANY response on the project despite requesting a status from the recruiter several times withing those 2 months. I don't mind if the project potentially wasn't good for them. I do care when they don't even let the candidate know. They just disappeared. That's very bad and truly incompetent! I wouldn't recommend to anyone applying for an engineering position at Uber in the Netherlands
