2 Supervisors asked me general questions for about 20 minutes. The interview was smooth and comfortable. They tended to be very interested in hiring me, show me around in the office and told me that for sure I will get the result by early next week. But no response, so I e-mailed them politely to get an answer. They never reply to me again which make me feel they are not professional. "Yes" or "No" is an easy answer. They just ignore my e-mail and never call me back.
