Was contacted by HR and had an initial "screening" interview that lasted about 15 minutes. Then I had a second phone interview that lasted about half hour with a would-be supervisor, who was actually really great. Next had an in-person interview (about an hour), which required traveling to DC. The interview did not go as well as I would have wanted. However, the interviewer still instructed me to provide two writing samples even though she already knew she was not interested in me. I emailed the samples as soon as possible. I also wrote thank you emails after phone interviews and even hand wrote and mailed a thank you note after the in-person interview. Their communication with me stopped after the in-person interview. I thought this was very rude considering they were aware that I took a very taxing trip to DC (on my own buck) to meet with them. I even followed up about a week and half after I submitted my writing samples. I am sure this organization is doing great work and that everyone is perfectly nice (including HR) but I am not impressed by an organization that cannot take the time and consideration to reject a candidate who went through 3 interviews, sent both email and written thank you notes, and took the time to follow up with you. Had I gone through the first interview and not heard back, I would not even think about it too much, but three interviews at least deserves a one line rejection email. To conclude, although things did not work out with this organization, I know I showed a high level of professionalism throughout the interview process, but I feel the company fell short in their level of professionalism towards me.
