This Google L4 interview experience guide pulls together what SWE III candidates reported in 2025 and 2026: how the loop runs, what they were asked, and where offers slipped to L3. The L4 loop is mostly coding, but the bar is high and follow-ups decide a lot. Run a Google-style mock with an experienced interviewer before yours.

Google L4 is the Software Engineer III level, usually for engineers with 2–5 years of experience. In Bengaluru it pays about ₹75 LPA in total, based on Levels.fyi averages: roughly ₹42 LPA base, ₹28 LPA in stock and ₹4.6 LPA bonus.

Stage | Length | What candidates report
Recruiter call | 30 min | Level check, timeline
Phone screen | 45 min | 1 coding problem, sometimes skipped
Onsite | 4 x 45 min | Coding, Googleyness, maybe design
Hiring committee | No interview | Decides hire and level
Team match | 1–3 calls | Then the offer

The Google L4 Interview, Round by Round
Technical phone screen
A 45-minute coding interview in a shared doc. You get one problem, often with a follow-up that changes the constraints. Several candidates said the phone screen was skipped for them, either because they'd interviewed at Google recently or because they had a competing offer with a deadline.
One India candidate in 2025 said it helped to "drive" the interview. That means stating your plan, checking it with the interviewer and narrating as you code, instead of waiting to be asked.

The onsite: two possible formats
Google L4 onsites come in two shapes, and some candidates in India were given a choice:
- Three coding rounds + one Googleyness and Leadership round
- Two coding rounds + one system design round + one Googleyness and Leadership round
If you're offered the choice and your design experience is thin, the three-coding format is usually the safer pick. If you've built and scaled real systems, the design option lets you show it.
Rounds don't always happen in one block. A May 2026 candidate had two rounds first, and the remaining two were booked only after feedback from the first pair. Another candidate in Bengaluru was given two extra rounds when the first set came back mixed.
Coding rounds
Most L4 coding rounds are medium-hard problems with at least one follow-up, and some rounds have two or three questions. One Bangalore engineer with 6 years of experience reported two questions in three of their rounds and three in the other two.
What candidates reported being asked:
- Hard dynamic programming. One offer-holder got LeetCode's Burst Balloons in an onsite, solved it, and still missed an edge case.
- Graphs and trees. BFS and DFS with extra state, shortest paths and tree traversals come up often.
- Repeated questions. One candidate noticed a 2024 question that had also been asked in 2022, so recent question lists are worth working through.
The same offer-holder focused heavily on graphs, trees and segment trees, their weak areas, and none of those came up. Breadth across common patterns matters more than going deep on rare ones.

Googleyness and Leadership
This 45-minute round mixes past-experience questions with hypothetical scenarios. One fullstack candidate in India opened with "Why Google?" and then got several questions about handling conflict with other teams. Another candidate used STAR answers and jotted notes during the round to keep their stories structured.
At L4, follow-ups and edge cases separate hire from no-hire. Practise a Google L4 coding round with a FAANG interviewer →
Downlevelling: When an L4 Loop Ends at L3
The hiring committee decides your level after the loop, and it can come in lower than the role you applied for. A 2026 write-up described a candidate in India who applied for L4 after working at an SDE-II level elsewhere, got a strong signal on the phone screen, sat seven rounds, and was offered L3 before being rejected. People applying for L5 sometimes get an L4 offer the same way.
What usually causes it is inconsistency. One strong round and one shaky round reads as "not yet L4" to a committee that only sees the notes. Missed edge cases, needing too many hints and thin follow-up answers all pull the rating down.
Timeline
Expect roughly six to ten weeks from first recruiter call to offer. Gaps are common: one candidate waited 25 days between clearing the phone screen and starting onsites, with a new recruiter. Interviews also get rescheduled at short notice, sometimes on the day itself. After the committee approves you, team matching can add one to three weeks.
How to Prepare for the Google L4 Interview
- Cover common patterns widely. Arrays, hashing, BFS/DFS, binary search, heaps, intervals and DP account for most reported questions.
- Practise on recent questions. Candidates say Google repeats questions over time, and LeetCode discussion threads collect them.
- Practise the follow-up as hard as the first answer. After each problem, ask yourself how you'd handle a 10x larger input or a changed constraint.
- Decide on the design format early. If your loop includes system design, prepare one mid-sized design end to end, such as a URL shortener or a rate limiter, at L4 depth.
- Do mock interviews in the real format. One L4 offer-holder did more than 20. Our Google mock interview guide explains how to set them up.

FAQs
How many rounds are in the Google L4 interview? Usually a phone screen and four onsite rounds. Some candidates get extra rounds when early feedback is mixed.
Is there system design in the Google L4 interview? Sometimes. Some L4 loops are three coding rounds plus Googleyness, others swap one coding round for system design.
What questions are asked in the Google L4 interview? Candidates report medium-hard DSA problems with follow-ups, including hard DP like Burst Balloons, graph and tree problems, and Googleyness questions such as "Why Google?" and handling conflict with other teams.
What is the Google L4 salary in India? About ₹75 LPA in total in Bengaluru: roughly ₹42 LPA base, ₹28 LPA stock and ₹4.6 LPA bonus, per Levels.fyi.
Can I be downlevelled to L3? Yes. The hiring committee sets the level from all your feedback, and uneven rounds can lead to an L3 offer.
How long does the Google L4 process take? Typically six to ten weeks, including gaps between stages and team matching.
Get Ready for Your Google L4 Loop
Google L4 is mostly coding, but the committee is looking for consistency across every round, with clean solutions, handled edge cases and strong follow-ups. A 1:1 Google-style mock interview on Intervue puts you through that format with a FAANG interviewer and ends with written feedback on what to fix.
