At a career fair there are two types of job seekers, ones with low experience (Elow) and those with high experience (Ehigh). 70 Elows arrive per hour and 30 Ehighs arrive per hour. The Elows first meet with a coach to go over their resume and to get interviewing tips. Coaching takes 10 minutes and there are 11 coaches. The Ehighs skip coaching and go directly to interviews with prospective employers. There are 40 employers doing interviews. Each interview with an Elow takes 15 minutes. Each interview with an Ehigh takes 30 minutes.
