The whole process took about 20 days, from the application to the offer letter. Three rounds of interviews and a case study. The first interview was with a screen call, the second interview was with the position supervisor, and the third was with two other supervisors and operators who were associated with the jobs client. The case study was easy if you understood the concept of what they wanted. I declined the offer due to low pay, and their unwillingness to negotiate any part of the compensation package, wage, benefits, or signing bonus.
