What a job interview! This is really well written erotica. Of course you will not have a great depth in the main characters. But I suppose this is expected. The book is like 30 pages long and 85% of it is just about sex. 
 Anyway, there is Elle who is a natural submissive and maybe she trusts too much her future bosses and there are also Boss A (Cunningham), Boss B (Jonathan) and a guy who makes a really terrible coffee and seems to be frustrated Elle is around (Nolan). 
 Not much feelings. Everything seems to be clinical and for one purpose. Although it is still weird why Elle was chosen and what is Nolan problem. Who is this guy?
