I got contacted through email asking when I was available for a 10-15 minute interview. Gave them my number and agreed we would call 10:30 the following day.
Never got a call from them, sat and waited for an hour extra.
Sent a mail telling them I never recieved a call, and if some other time would be better suited.
No response to this day.
I applied online. I interviewed at Cal Engineering Solutions in Mar 2022
Interview
Applied online and waited more than two weeks for a call back. Easy questions, but the response time was horrible. Best of luck going through the process, you're better off looking for another job that can call back faster.
