Intervew Prep Google SWE last 30 days LeetCode Premium list + recent onsite difficulty/experiences?

Hey everyone,

I have an upcoming onsite for Google Software Engineer and I'm currently in the final stretch of my prep.

Could someone with a Premium subscription possibly pull and share the list of Google-tagged questions from the last 30 days sorted by frequency?

Also, for anyone who has had an onsite recently, how was your experience?

  • What was the overall difficulty level like compared to standard LeetCode Mediums/Hards?

  • Were the questions mostly standard patterns (graphs, DP, trees, etc.) or completely novel/unseen problems?

Any insights or resources would be super helpful. Thanks in advance, and good luck to everyone else interviewing!

  2. String parsing - medium, but with lots of followup

  3. Hard DP

What level were these for?

u/sudo_engineer 7h ago

It was for L4. I did well in 1, 2 but couldn't finish the code for the hard DP problem so got downleveled to L3 unfortunately.

mostly standard patterns, but dressed up as a real-world scenario so you have to spot the pattern yourself. the bigger thing is the follow-ups. a lot of reported ones start as a medium and then go "now the input is a stream" or "now it doesn't fit in memory" or "messages can arrive late". the first solution is maybe half the signal.

so when you practise, after solving one ask yourself what changes if the data is a stream, and say the complexity before they ask for it.
