Agree with other review that interview process took almost 4 weeks, but I appreciate that they are very concerned about hiring the right people (I wish more companies worked this way). I am very excited that I now have the opportunity to work with a passionate group doing important work. I received another offer while I was waiting to hear back from them and they responded with an attractive offer. It my not be the highest salary but it was competitive and fair considering my experience. I was thrilled but in my opinion, the bottom line is who work with/for, not how much they are paying you.
