The Interview Process

A standardized big-tech loop runs a recruiter screen, often a timed online assessment, one or two technical phone screens, a four-to-six-round onsite, a committee-style review, then team match before an offer conversation.

Junior loops are mostly coding rounds. Senior loops trade some coding slots for a system-design round and a deeper past-work round. Staff-and-above loops add architecture and cross-team influence rounds, and coding usually shrinks to a single screen.

A seed-stage startup usually runs two to four conversations inside one to two weeks: a founder chat, a practical round on real work, and a short team round. The founder decides directly, with no committee and no fixed rubric.

Ask the founder or hiring manager, in writing, what each conversation is, who is in it, whether there is a practical or trial component, and what decides the outcome. Then prepare against that list.

Allocate practice in proportion to the round mix. A mid-level loop rewards coding reps plus one solid design round; a staff loop rewards assembled scope evidence, architecture breadth and cross-team influence stories, with coding kept warm rather than drilled.

Read all three problems before writing code, then attempt them cheapest-first rather than in the listed order. The given order is not a difficulty ranking, and banking the solves you are sure of protects points the clock would otherwise take.

A technical phone screen is a 45-to-60-minute remote call where a candidate solves one or two small coding problems in a shared editor with an engineer listening. It gates the onsite: the screener recommends advance or reject.

A recruiter screen decides whether you enter the pipeline at all. In roughly 25 minutes a recruiter confirms role fit, logistics and clear communication against an intake checklist, then records those facts so an engineering round can be scheduled.

A take-home README should carry run instructions that work on a clean machine, the scope you chose and why, the tradeoffs and known gaps behind it, and roughly how long you spent.

Sample cases are illustrations, not the grading suite. The hidden tests add boundary inputs and inputs at the constraint ceiling, and where scoring is per test, the problem score is the fraction of that hidden suite your submission passes.

Restate the problem in one sentence, then confirm the input shape, its realistic size, the behaviour on empty or malformed input, and the exact return value. Three or four scoping questions prevent solving the wrong problem and show how you take on work.

A work-sample round hands you existing code — a repository to pair on, a seeded bug to fix, a change to review — and scores day-one effectiveness: orienting, verifying, collaborating. An algorithm round scores invention from an empty editor.

A 45-minute system-design round runs in four beats: roughly 10 minutes agreeing requirements and scope, 5 on rough scale estimates, 15 sketching the high-level design and its interfaces, and 15 on one deep dive the interviewer picks.

A stated brute force gives you a correct floor to fall back on, proves you understood the problem, and turns optimizing into a visible improvement with a named cost. Silence while you hunt for the clever solution shows the interviewer nothing.

Reproduce the failure first, read the failing test as the specification, localise with evidence rather than guesswork, make the smallest change that turns that case green, then re-run the whole suite and say what you would follow up. Diagnosis before edits is the scored part.

A full-loop day is usually four to six scheduled rounds of 45 to 60 minutes, each with a different interviewer, separated by short gaps and often one lunch slot. Every interviewer writes feedback and the panel compares notes afterward.

The hiring-manager round tests durable fit rather than a sampled skill: what work you actually want, how you operate with ownership and feedback, and which rung of the ladder your evidence supports. The manager records that as their own scorecard.

Panel interviewers write independent notes and then compare them in a debrief, so two different versions of the same fact surface side by side and read as embellishment rather than fatigue. Keep the facts stable and correct any slip explicitly.

Treat a full-loop day as an endurance event: eat and drink through it, use every gap for a physical reset rather than revision, and ask for a short break when you need one. Fading after round three is the common failure.

A bar raiser is a trained interviewer from outside the hiring team who runs one round of the loop and files a separate scorecard. That write-up is weighted for long-term standard-setting and can block a hire the team wants.

Each interviewer first writes up their own evidence and a hire or no-hire score, independently. Those write-ups form one debrief packet, and the outcome is argued from that written record rather than from spoken recollection on the day.

Specificity and speed. Send it within about a day of the round, name one concrete thing that conversation produced, add one short line that closes a gap or states interest, and keep it under a screen.

Ask the recruiter for what they can safely confirm: which stage the decision was made at, and how long before you may reapply. Detailed per-round critique is rarely shared, so do not build your prep plan around it.

Wait out the timeline you were given, then check in about every five to seven business days, replying inside your existing thread. Two or three spaced, short nudges is the normal ceiling before you ask for a decision date instead.

A cooldown is an employer policy blocking reapplication for a set period after a decline, commonly six to twelve months. It is recorded against you as a person in the tracking system, so it can span teams, not just that one role.
