Proofpoint

The interviewer was late to the meeting and also was disrespectful to me. I don't recommend you to interview there. There are plenty of other companies out there which are better than this one.

Several meetings, they talked to me. I answered things back. Then again. It was very good. All and all it was basically talking, listening and answering questions. Then, we discussed salary and questions that follow. Answer too were quick.
