I applied through a recruiter I met who forwarded my resume to another recruiter who had a better fit for my profile. They then asked me to fill in a profile form asking for more information. Mainly about achievements and some personal experience. I was invited to take the PST. I passed the PST and was invited to round 1 interviews. I was a bit irritated by the recruiter as I had to constantly prompt her for information. "Did you receive the profile asking for additional information (after 3 weeks elapsed)". "Did I pass the PST exam (after almost 2 weeks)". "Have you scheduled the 1st round (2 weeks after being informed I've passed the PST". Needles to say I was a bit irritated by the communication especially because I was interviewing for other positions. The PST was not difficult just needed more time. I left the lengthy calculations to the end and ended up guessing about 3 of them as time had run out. Just has my first round interview and I'm waiting for feedback. The interview was ok. I studied but everything I read about structure flew out the window once I was sitted there. I was given some direction to solve the math problems. One interview was pretty awesome and the other difficult to read. He interrupted me a lot. Waiting to hear if I got past the first round. There is one more round to go.
