CodeSignal online assessment was received about 1.5 weeks from app submit. Completed OA Dec 24, then received invitation to interview Jan 24, exactly 1 month later. Two interview rounds: 1 hour Leetcode screen on Zoom, then if passed, a 3-round interview loop. Interview loop is 2 Leetcode rounds with current engineers, medium difficulty. Then behavioral is what you'd expect. Got the offer a little over 1 week later.
