Control Risks Manager interview questions

Was invited for an interview which I thought went very well. The entire process up to that point was great and I was really excited about the job opportunity. I was told I will get feedback in 2 weeks. However, it's been radio silence for over a month. I've sent emails & LinkedIn messages to follow up at two weeks intervals to 3 of their staff, all which went unanswered. Even if a decision is still being made, or there's been a delay, the polite thing to do would be to respond to my emails rather than ignore them. The experience has left a bitter taste in my mouth and would not recommend a company that feels it is too important to respond to potential employees. Means you will also likely be ignored as a staff!
