The hr rep spoke very bad English, had to repeat everything several times. The person couldn’t understand simple concepts, probably due to lack of experience or knowledge of the technology and the company. In addition, very rude and aggravated, in general unprofessional HR. Honestly, I don’t know who would want to continue to continue interviewing with the company after this.

I had the opportunity to take the process of chief of staff until the last step (case study). I discussed my case study with their CEO and chief of staff and send them my analysis. I have NEVER received any feedback. I find it absolutely disrespectful to go so far in a process, to invest so much time and above all to have the opportunity to talk to C-levels, without any feedback. The least you can do is reply to emails and share feedback; that's the minimum you can do as HR involved in an “innovative” scale-up. Make sure in your ITW process to ask for feedback, I just have the sentiment that they use my work for free.
