IBM Software Developer interview questions

The initial phone screen with the manager went very well. After being selected to proceed to the face to face interview, I was given a rather ambiguous assignment to create an email to a client, a slide deck / presentation on the project describing security issues, and a meeting agenda for the client. I'm very glad I had read some of the other reviews on Glassdoor; however, I was still not prepared for what actually occurred.

I applied online and received an email the following day from a recruiter within the company and was told to do a 3 hour online exam. He said if I had any questions just email him. I had a few questions before starting so I emailed him but never got a response. I did the online exam the following day. The online exam was very bizarre; there was no one on the other end and I had to record answers by speaking into my webcam. There was also 3 coding questions. About a week and a half later, I received an email from the same recruiter saying that I had passed the online exam and that he would call me within 48 hours to schedule an online whiteboard interview with one of their engineers. I never received a call from the recruiter and any email I sent to him was met with radio silence. Very unprofessional. I spent 3 hours doing their HireVue exam so the least I expect is to at least get a followup email from the recruiter that they changed their mind or something instead of just ignoring me.
