Let me break down the ENTIRE process: This is a long post, so sit tight. First thing, everyone gets a CodeSignal assessment. No CGPA filter. 70 minutes for 4 questions. Q1 & Q2: Leetcode easy Q3: Implementation heavy with edge cases Q4: Between medium and hard (needs optimal solution) My suggestion? Tackle them: Q1 -> Q2 -> Q4 -> Q3 Patterns my friends and I noticed last year: Sliding window, Two pointer, Hashmap, Stack, Tries Aim for at least 500+/600 to be safe. Then the real fun begins… Every. Single. Interview. Matters. None are a formality.
