E4, 3 YOE. Got the no on Thursday.

Screen: Valid Palindrome II + a merge intervals variant. Easy enough, moved on in a week.

Onsite:

• Coding 1: Minimal Board Length for Holes, binary search on the answer. Got it but burned time on the check function. Second q was alien dictionary, half done.
• AI coding: their editor with the assistant. Small tests passed, last suite was a stress test and mine timed out. That one hurt.
• SD: news feed type thing. Felt ok.
• BQ: conflict, a project I'd redo. Lots of "what would you change".

Recruiter said coding signal was mixed. Pretty sure the AI round and the half finished alien dictionary did it.

Is the cooldown still 12 months for E4 or did that change?
