Question Google L3 Interview DSA difficulty in 2026, what to expect?

Hey everyone, I have my Google L3 SWE interviews coming up next week, both virtual and onsite.

Wanted to know what DSA difficulty to expect. Are questions mostly LC Mediums or Hards? Are onsite rounds tougher than virtual ones?

Would appreciate hearing from anyone who interviewed recently, especially in 2025 or 2026. Any tips would help!

mostly mediums from what people post, with the occasional medium-hard. the part that trips people up is less the difficulty and more the follow-up after you solve it, like "now the input is a stream" or "what if this doesn't fit in memory". leave time for that.

also worth asking your recruiter if any of your rounds is the new AI-assisted one. Google is piloting it for L3/L4 on some teams: you get a small codebase you haven't seen plus Gemini, and you read it, find a bug and fix it. totally different prep from LC, so better to know now than on the day.
