I applied online. I interviewed at Billups in Mar 2026
Interview
After 4 stages & 3 weeks of radio silence, I received a generic email to say the company was ‘taking a different direction’ regarding what they were looking for. The 4th stage interviewer clearly was not on the same page as the rest of the employees who interviewed me. Wasted a month interviewing with them.
