Spreetail Internship interview questions

A very disappointing interview process. There are at least 2 rounds. First with the HR and second with the manager. Having performed nicely in the first round and reassured by the HR that they will proceed me to the next round on the phone that they will send me an email to confirm the date of the second interview, the HR department has not responded to me. Having been waiting for their responses for 3 weeks, they just told me that the position is filled after all.

It is a behavioral type interview process. They ask many questions that could have the same outcome but they are quick with their responses on whether or not you had gotten the job.
