Why Does A Potential Employer Go Radio Silent? 

I am often asked why a firm or company who seemed interested would suddenly cease communications in the recruiting process. There could be a few things going on:

1. The potential employer has higher priorities at the moment than hiring. Management could be caught up with demanding work, and HR could be tasked with more urgent matters.
2. The potential employer is restructuring or perhaps hit with a job freeze. There is uncertainty over the role, so they don’t want to speak out of line.
3. The hiring manager is on vacation, has left, or changed roles. Perhaps your internal champion is no longer there or no longer holds sway.
4. The potential employer is more interested in someone else — perhaps an offer has been made already, and the employer wants to see how that goes first. 

If you have been regularly checking in to no avail, I would advise you to stop for a couple weeks.
