Pix4D interview questions

Online coding (hackerrank style) with many simple problems. Non-technical phone screen with SWE. Got homework ~3-4+ hours, not programming competition hard but lots of smaller pieces (e.g. build project to this spec). *Horrible* experience with radio silence after that, no feedback, no rejection letter, nothing. If you make people donate 6 hours (including all rounds) of your time for free, have the dignity to send at least one sentence e-mail. I warned people I know at EPFL to avoid Pix4D.

After a lengthy interview process, (i.e several rounds of phone interviews, taking time off work, traveling to SF, and interviewing in person for several hours) I was met with complete radio silence. It's completely unprofessional and rude to ask someone for their time and not give them a response. I went from having respect and admiration for Pix4D, to seeing how dysfunctional and inept the company truly is. To all the job seekers out there, save yourself some time and apply elsewhere
