Very comfortable interview face to face, myself along with Paul and Ryder, again similar to the phone interview but a bit more about the role and myself as a person, ask things like what I see myself doing and bringing to the company, what I know about the company. Then received a call back to go for a "trial" where I went out with Hannah on a couple of jobs to get a feel for the position and chance to ask more questions with somebody doing the job daily, got back to the office and was offered a position.

If a procedure requires 400mg of NaCl and the allowable variation +/- 1%, what is the allowable variation in mg? If you have three test coupons and the results were 2610lbs, 2500lbs and 2560lbs how would you find the average? Standard deviation?
