Clever Devices Software Engineer interview questions

Following a phone screening, where the interviewer seems to decide up front without listening to me that much as he was inpatient invited for 2.5 hours HackerRank - solved 3 questions - each passed all unit tests. OMHO I could not do better that that. They have never got back to me until I've approached them after about 10 days, and found out that the hiring manager (no name of course) has EXACTLY returned that day

A recruiter from Clever Devices Reached out to me on LinkedIn in late 2017 indicating that they were hiring multiple developers. After some back and forth they asked - or rather told - me to send them an updated resume. I did not hear back and assumed they'd moved on with their search. Months later, I got a call from the same recruiter, who seemingly did not remember our exchange, because they introduced themselves as if we hadn't talked, and we discussed the expansion of their Toronto office and a desire to hire more developers, mentioning that my resume was on file and that I stood out. After a brief screening, they emailed me to ask for an updated resume and provided a (very simple) technical test for me to complete. I sent my response to the test over on Sunday and was told by a colleague (CC'd on the email) that the original recruiter was out of town doing training and would respond within a few days. A month later, I had heard nothing. Respecting a candidate's time is evidently not a priority for this company.
