I applied, I had multiple interviews, I got reject because I was bad during them.

Anyway, the interview process was so janky it decreased my confidence in their success.

I’ve heard many folks get rejected and leave with a bad taste in their mouth. Interviews should make you feel like you’ve failed due to you not being quite there while still recommending friends to apply (“I didn’t make it but you should try to apply!” Vs “i felt like I had the privilege of even talking to the dude and then got ghosted”).

Instead of trying to get into Mistral, why don't you make your own Mistral?

Not easy as it sounds yes, but it is better than throwing your CV into the ATS void 1000 times (the wrong way to apply for a job btw)

Mistral have no moat as it seems except some 'regulatory' moat.
