I was a contractor for Dynalabs previously so I had an existing relationship with the owners and management. This, obviously, gave me a leg-up on any competition. The interview was brief and I was basically pitched the job rather than having me pitch myself. There were no technical questions but I believe I was an exception having already been familiar with the company.
Overall it was a positive experience. One thing to note - the offer was contingent on passing a HAIR FOLLICLE DRUG TEST. This was only brought up AFTER negotiations, I had resigned from my other job and accepted the offer. In my opinion, they should have brought this up much earlier in the process.
