Presales / Solution Engineer Interview Prep & Rubrics

Discovery, proposal and RFP work, demo storytelling, commercials, and live objection-handling role-plays.

The loop, in order

Presales & Solutioning21 questions · 7 topicsSolution-engineering and presales-architect interviews, which uniquely test commercial instinct and live communication alongside technical depth.
Architecture & Tech Leadership21 questions · 7 topicsRounds specific to senior, staff, principal, and architect titles, where the subject is judgement and organisational impact rather than code.
System Design70 questions · 12 topicsOpen-ended design rounds broken into the building blocks they draw on, plus full case studies worked end to end with explicit trade-off reasoning.
Product Management22 questions · 7 topicsThe PM loop as it is actually run: product sense, analytical, execution, and strategy rounds, each with its own scoring rubric.
Behavioural & Culture Fit25 questions · 8 topicsThe round candidates most often under-prepare, treated as a skill with structure rather than small talk, including the rubric interviewers score against.
HR, Screening & Offer19 questions · 6 topicsThe recruiter and HR rounds that gate the technical loop and decide your compensation, where most candidates improvise and lose money.
Working in a Domain6 questions · 3 topicsDomain knowledge as a skill rather than as a subject: why it decides between two technically equal candidates, how the vocabulary gates entry, and how to acquire it deliberately instead of absorbing it over a decade.
Banking & Financial Services27 questions · 11 topicsHow a bank works underneath the app: the ledger that must always balance, the rails money moves over, the identity and financial-crime controls wrapped around it, and the regulatory reporting that constrains every design decision.
Healthcare & Life Sciences19 questions · 7 topicsClinical and payer systems, where the record is legally significant, interoperability is decades of overlapping standards, and interrupting a clinician has a real cost.
E-commerce & Retail23 questions · 9 topicsThe path from browse to delivered and back again, where inventory is the central consistency problem and every edge case is a real order belonging to a real person.

A headquarters team in another time zone keeps making decisions that land on your team. Tell me how you handled it.

Treat it as a process gap, not a grudge. Find out where and when decisions are made, get your team's constraints in front of the deciders before the meeting through short written proposals with a comment window both time zones can reach, and escalate a specific costly decision, not the people who made it.

Design an experimentation and feature-flag platform: assignment, exposure logging and a kill switch.

Evaluate feature flags in an SDK from a cached ruleset, assign users by hashing a per-experiment salt with the user id so assignment is sticky, log exposure where the arms first diverge, gate readouts on an automated SRM check, and make the kill switch a top-precedence rule that works with the control plane down.

Design a notification system that sends 50 million messages a day across email, SMS and push.

A notification system at 50 million a day is sized by bursts and provider limits, not its average of about 580 a second. Accept with an idempotency key, apply preferences once, fan out to per-channel queues with transactional and bulk lanes, rate-limit each provider, and never fail over blindly on a timeout.

How do you use AI tools in your daily work, and when do you refuse to trust an LLM's answer?

Describe your use of AI tools by task, each with its check: reading cited lines, running code, confirming APIs against the docs for your version. Refuse any answer you cannot check cheaply or that is costly to get wrong, keep restricted data out of unapproved tools, and back it with one real catch.

Ownership And Impact5 minmid, senior, staff

hardDesignScenario

Rate-limit an LLM gateway where one request can cost a hundred times another.

Rate limiting an LLM gateway by request count fails because cost is tokens, and output tokens are unknown at admission. Budget tokens per tenant, reserve input plus expected output, settle against reported usage when the stream ends, cap concurrent streams, and cancel upstream on disconnect.

Design a distributed job scheduler that runs every job once, and on time, even when workers die.

A distributed job scheduler cannot promise exactly-once execution when workers die mid-job, so it promises at-least-once with idempotent jobs. Materialise each firing as a run row, claim it with a lease and heartbeats, judge time by one clock, and key side effects on job id plus scheduled time.
