Interview
Had phone interview first which lasted about 15 minutes. Recuriter was very prompt in setting up an in face interview with the hiring manager. Next interview happened the very next day with 2 hiring managers. Very professional and went very well. The third interview was then with 2 more hiring mangers and HR. The final interview was another team 2 of hiring managers. Took about a week before I received the offer which is contingent upon passing the background check and drug screen.
You could tell by the interviews that they are a results oriented company. Mentioned that in the interview as well. They ask situational questions based on your passed experiences. Interview process took 3-4 weeks.

Ghosted After Interview! Disappointing Candidate Experience
The initial outreach was fast, and the role sounded like a good match. The interview was scheduled quickly after the recruiter’s text, which I appreciated. After a 30-minute interview with the hiring team, I never heard back! NO update, no feedback, nothing. I followed the process in good faith, but the lack of any follow-up was unprofessional and left a negative impression of the company’s hiring practices.
Respect candidates’ time by communicating decisions promptly. Even a short rejection email is better than silence. A professional process should value people whether they’re selected or not.
