I did a phone screening and then 2 back to back 45 minute interviews with the team there. I sent a follow up email thanking them for their time. It has been one month and I have not heard anything back. I understand that interviewing does not mean you will get the job, but I at least expected some sort of communication given the 3 hour mid-day interview I had. It gives the impression that your time is not valuable, which is best learned now rather than after accepting a job.
