I was contacted by a sales manager shortly after submitting my application to take part in a phone screening. The phone screening was about 25-30 minutes and he asked me basic questions about my prior experience, skill set and ambitions for the future. He then gave me a run-down of the job and asked if I was still interested. And I was!
I was then contacted a day later by one of their recruiters to schedule an onsite interview. I took a half day at work and took part in the 2.5-hour onsite interview. I met with five people back-to-back who were representative of various levels of management, i.e. sales manager, sales VP, sales training manager, etc. The only tidbit I have for this part of the process is that one of the team members who interviews you will likely exclusively ask work culture-type questions to see if you would mesh well with team. This part wasn't hard, but I had never been asked about my feelings on work environment preferences. I viewed this particular conversation as very important as it showed the company's commitment to employee satisfaction and a rich culture.
The next day, I was invited back to interview with the CEO, Isaac. While interviewing directly with the CEO sounds intimidating, it was actually a very pleasant experience as Isaac is easy going, friendly and incredibly smart. I thought this interview went well but was a bit nervous leaving my "final" interview. The next day I was contacted by the person I did the initial phone screening with and met officially during the onsite interview with an offer. The offer was great for someone just starting out in sales and I enthusiastically accepted!
Some people mentioned that the interview process was disorganized or not good. Well, as of June 2016 I can say Justworks has it figured out because it was the most expedient and thorough interviewing process I have experienced to date.
