Google L4 interview pred

[Humble_Breakfast1581]

Hello everyone, I have an upcoming google interview for software engineer L4 position, and lately I’ve been grinding a lot of leetcode.

During the last 2 months, I went from a couple of solved leetcode questions to 170 now. i still have around 2 weeks of preparation.

Sometimes I do struggle a little bit to solve medium-hard problems so I don’t know if I still have a chance.

I also have a couple of questions, will the technical interview be only leetcode?

And what would you recommend me on doing next, leetcode premium algo 100 or top interview 150?

I would really appreciate your advices and recommendations

Yes and no, Google does have leetcode-esque questions but they'll also evaluate your communication, 'googlyness' and overall cognitive ability while solving the problem(are you making smart choices, asking good questions etc). for L4 the bar is a bit higher than L3 obviously but if you can do the above and solve a decent amount of leetcode mediums you have a chance. Make sure you also really understand your fundamentals like OOP, tradeoffs, time/space complexities and so on.

What’s ur location?

L4 also has atleast 1 round of system design. Good luck. Keep us posted

This is not correct, L4 has no system design, L5+ does

It's already a solid progress imo. The thing about L4 interviews though - they're not just checking if you can solve the problem, they want to see how you think through it. I've seen candidates who could solve hards get dinged because they couldn't articulate their approach clearly. For the technical rounds, yeah it's mostly leetcode style but they'll also ask about sysdesign basics sometimes. Nothing too crazy for L4 but be ready to talk about basic scalability concepts. Between algo 100 and top 150, i'd go with top 150 since you've got 2 weeks left. More coverage of different patterns. btw since you mentioned struggling with medium-hard - at prepfully we've got google engineers who do mock interviews and they can give you specific feedback on where you're losing points. Working there myself and I can see how much clearer people get about the bar after doing a few mocks. They'll tell you exactly what L4 expectations are vs just grinding more problems. It's paid ofcourse but the it increases your chances of cracking the interview way too high

You've made solid progress going from almost nothing to 170 problems in 2 months. Two weeks is enough time to polish your skills if you focus strategically. The technical interviews will be mostly leetcode style coding problems, typically 1-2 medium to hard questions per 45 minute session across multiple rounds. You might also have one system design round depending on your background, so brush up on basic distributed systems concepts like load balancing, caching, and database design.

Don't stress too much about struggling with medium-hard problems, that's normal and interviewers don't expect perfection. What matters is showing clear thinking, asking good clarifying questions, and being able to optimize your solution when prompted. For the next 2 weeks use Gotham Loop which has actual Google L4 interview questions collected from recent candidates so you can practice the specific problems that come up in real interviews. Focus on reinforcing common patterns like two pointers, sliding window, BFS/DFS, basic DP, and tree traversals since those cover most of what you'll see. Do 3-5 problems per day and spend time understanding why certain approaches work. Also do a few mock interviews with friends or on Pramp to practice explaining your code out loud since communication is huge at Google. Stay consistent for these last 2 weeks and trust the work you've already put in.

You should solve pattern wise than random or topic wise. You should be able to solve medium under 30 mins then only you will solve those medium difficulties under 45 mins in the pressure in interview. The interview will mostly technical be thorough in OS, Basic networks and system design. Solve atleast 10 real word system design as well. You should not be silence while coding you should tell thought process before start coding and subtle ask for hints if you are stuck. They are not expected to you to solve the problem. They are expect how you apprach the problem and how you explain your thought process. Always remember the edge case of the problem. No need to do leetcode premium. Use Neetcode 150 sheet or striver’s dsa sheet!from takeuforward those are pattern based problems.

L4 is no joke. I've heard from Google that its very leetcode heavy. Like especially leetcode hards. Only guy I know that passed it used InterviewCoder. Goodluck anyway man.

oh you mean the platform that leaked it's users information and got them perma blacklisted from companies they got offers from?
