Waymo software engineering interview questions

The Process

Five rounds, and the people who decide never meet you

01

30 minPhone call

Recruiter screen

Waymo runs Alphabet's process with its own twist. The recruiter decides which specialisation you interview for, and that choice is hard to undo later.

Pick your specialisation deliberately.
Perception, planning, simulation and infrastructure run different loops with different bars. The recruiter writes yours down on this call.
Say whether you want the car or the cloud.
Half of Waymo engineering never touches a vehicle. The onboard and offboard sides are separate careers with separate panels.
Ask which level the role is mapped to.
Waymo uses Alphabet's L3 to L7 ladder, so the level named on this call sets the band before you have written a line of code.

02

45 to 60 minShared doc

Technical phone screen

One or two problems typed into a plain shared document with no editor, no autocomplete and no run button. Waymo kept that part of the Google process exactly as it was.

Practise without a compiler.
Syntax errors you would normally never notice become visible here, and interviewers do count them.
Say the complexity before you type.
The screen is short. Stating the approach and its cost first is what leaves you room to finish the code.
Expect one question about physical reality.
Sensor rates, timestamps and dropped frames turn up even in a generic coding screen, because that is the data everyone works on.

03

4 to 5 roundsOne dayVirtual

The onsite loop

Two coding rounds, one domain round on the area you were slotted into, one design round, and a general round on how you work. The domain round separates candidates.

Bring safety into the design round unprompted.
Every Waymo system has a failure mode that ends with a vehicle doing something. Say what happens when your component stops responding.
Know how your work gets validated.
Simulation, structured testing and public road miles are the three levers. Saying which one you would use, and why, reads as senior.
Numbers, not adjectives.
Latency budgets, sensor rates, miles between events. Waymo engineers argue with figures and expect the same back.

04

1 to 2 weeksPacket reviewNo candidate input

Hiring committee

Your interviewers do not decide. Written feedback is assembled into a packet and read by a committee of engineers who never met you, exactly as at Google.

Your write ups are the only evidence.
Anything you said that the interviewer did not record does not exist. Repeat your key point at the end of each round.
An even loop beats a spiky one.
One outstanding round next to one weak one usually stalls the packet, because the committee is looking for consistency.
A missing signal is not neutral.
If nobody scored your design ability, the committee tends to ask for another round rather than decide without it.

05

1 to 3 weeksThen comp review

Team match and offer

Approval and team matching happen after the committee, and the pay review is separate again. The grant is Alphabet stock, so the equity number is a public share price rather than an internal one.

Team match can add weeks.
Passing the committee is not an offer. You still have to be wanted by a specific team with a specific opening.
Check what the units actually are.
They are Alphabet GOOGL units with a public daily price. There is no funding round valuation to ask about, no strike price and no liquidity tied cliff.
The bonus is a target, not a promise.
Alphabet style annual bonuses move with company and individual performance, so treat the headline total as a range.

Levels and Pay

Most of the offer is Alphabet stock with a public price

Pick a level to see how the package splits, what changes by city, and what the loop actually asks of you at that band.

Mountain View

New York

Level	Experience	Total comp
Software Engineer IIL3Entry	0 to 2 yrs	~$235K

Waymo pays one national band. The same Software Engineer, Driving Behaviors requisition is listed for Mountain View, San Francisco and New York at a single range of $175,000 to $215,000, so these tabs are here to show you the number does not move, not to move it.

FAQ

Common questions

How are the questions sourced?

Directly from engineers who interviewed at Waymo, then cross validated against other intel sources into a stack ranked list.

How often are questions updated?

We add new questions every 7 days and retire each one after 14 days, so the bank turns over twice in the window it covers.

Does Waymo ask LeetCode questions?

Yes, at Google's bar and in a plain shared document. Graphs, grids, heaps and intervals dominate, and the domain round is layered on top rather than replacing them.

Can I use AI tools in the interview?

Not in live rounds. Waymo follows Alphabet's candidate policy, and the shared document leaves an obvious trail when someone stops typing.

What is the hiring committee?

A panel of engineers who never met you and decide from written feedback alone. Your interviewers recommend, the committee approves, and the two often disagree.

What does Waymo pay a Software Engineer III?

Around $315K in Mountain View, and the same in San Francisco or New York, because Waymo pays one national band. About 29 percent is Alphabet stock at the public daily price, plus a target bonus.

How long does the process take?

Six to ten weeks. The loop itself is quick, but committee review, team match and the separate pay approval each add time.

Is this just for Waymo?

No. GothamLoop covers 120+ companies including OpenAI, Google, Meta, Amazon and Apple.
