The whole process took about four weeks and I talked with 4/5 different HR reps so that was confusing. I applied for a different job and got an email from HR to do a half hour phone screening and then a few days later I received an email to do the 3 hours of assessments. That was honestly the worst part of whole process, somehow worse than any standardized test I have ever taken but maybe that's because I didn't understand going into it how long it would take.
A week later I got an email letting me know I was no longer being considered for the position but they were interested in inviting me to a final interview for the Quality Manager position. I decided to give it a try since I had already invested so much time in the process. The final interview was three hours and consisted of an overview of the company and demo of the products, a one-on-one with a current employee in the role, a case study type interview with another employee, and a normal interview with an HR rep. Honestly the whole day felt very relaxed and wasn't stressful. I had good conversations with everyone.
Afterwards, the HR rep let me know I would hear back within 2-3 weeks. They contacted my references and did a background check and I had an offer 1.5 weeks after the final interview. In my conversation with the final HR rep, they were very transparent about what the salary offer would look like and I was pleased with the end result. I really appreciated the constant contact I had with the company. Even though I was passed between several different people in HR, I always understood what the next step was and when I would hear back and then they always got back to me sooner than they had anticipated.
