I submitted an application with my resume. A week later, I received an email to take an IQ test within three days. I took the IQ test; it was pretty long, and the countdown timer didn't help. I think I guesstimated about two questions.

I scheduled a phone interview with an employee who is also a Software Engineer. This is where it started making me uncomfortable.

He would ask technical questions about coding, just like all other software companies ask. With the exception that when I would hesitate to think or ask for some time to think it through, he giggled and laughed. Or when I would ask for a clarification of his question, he would again giggle and laugh.

After about fifteen to twenty minutes of this torture, I asked him what was so funny. He said the situation was funny because usually, other applicants know what he is talking about. So, I'm not a CS major, but I decided to give the position a shot because I have some programming experience.

At the end of the interview, I had already decided in my mind that I did not wish to work for Bloomberg. He asked me if I had any questions about the position or the company. I said no, I had no questions. He then said to me, "So you know EVERYTHING about the position and the company. You have absolutely no questions." Something to that effect. (He actually emphasized that word.)

I explained to him that after this interview, I had decided not to pursue the position with Bloomberg. He then responded by saying that not everybody is suited for the position and that the interview is a two-way interview. I agreed.
