Puh not good signs at all.
I mean even the normal people we get in interviews have no clue, like 80% are just ignorant.
I stoped an interview after 5 minutes: when i asked what ls -ahl is doing, he started telling me how he vibe/ai codes stuff and thats his workflow. Okay if you don't know the basics, guess what? everyone can replace you or at least i'm not hiring you (i only told him thats not what we are looking for and thanked him)
we are doomed :D
