ReadTL;DR
7shifts builds team management software for restaurants, scheduling, time clocking, tip payouts, and payroll for hourly workforces, and its Software Engineer interview is a practical, friendly, remote-first process. Expect a recruiter screen, a hiring manager conversation, a technical round with hands-on coding at an accessible bar or a take-home, a system design or architecture discussion for senior roles, and a values-focused final round. The stack is PHP on the backend with TypeScript and React on the front, plus native mobile apps, and design questions live in the scheduling domain, constraint-heavy schedule generation, labor compliance rules, and syncing with point-of-sale systems. The culture is Canadian-rooted, humble, and product-focused, and loops usually complete in 2 to 4 weeks.
2-4 weeks
Sample Questions
Design the data model for schedules, shifts, and availability
Relational modeling with recurring availability, multi-location employees, and efficient queries for the schedule-builder view.
Fix the performance of a slow schedule-view query
Read the query plan, add the right indexes, and restructure N+1 access patterns, practical optimization at product-company scale.
Build an API for employees to swap shifts
Endpoint design with eligibility validation, manager approval flow, notifications, and audit history, product judgment made technical.
Generate a week's schedule under availability and labor constraints
Constraint-satisfaction pragmatism, heuristic generation, hard versus soft constraints, and validating jurisdiction-specific labor rules.
Handle time-clock punches from a tablet that went offline
Offline-first sync, conflict resolution for overlapping punches, and integrity when the data feeds payroll.
Tell me about receiving feedback that changed how you work
The humility screen in action, genuine reflection and applied change matter more than the polish of the story.
About the Interview Process
7shifts runs a candidate-friendly process with clear communication and respect for your time. Technical evaluation is practical, code you would actually write on the job, discussed collaboratively, and senior candidates add an architecture conversation about scaling a multi-tenant SaaS serving tens of thousands of restaurants. Values rounds carry real weight, the company protects a humble, supportive culture and interviews for it explicitly. Remote interviewing is the norm across Canadian and US time zones.
Recruiter Screen
Background, location and time-zone fit, and role overview. Compensation philosophy and ranges are shared transparently early.
Hiring Manager Conversation
Experience walkthrough, motivation, and mutual expectations, with technical texture, what you have built, how you work, and what you want next.
Technical Round / Take-Home
Live practical coding or a respectfully scoped take-home, building or extending a feature slice, reviewed together with discussion of choices and trade-offs.
System Design (Senior)
Architecture discussion for senior roles, multi-tenant data modeling, schedule generation under constraints, POS integrations, or scaling the notification pipeline.
Values & Team Round
Conversation with future teammates on collaboration, feedback, and culture fit, an honest two-way check on the humble, supportive environment.
Timeline
2 to 4 weeks with prompt scheduling and same-week decisions after finals.
Tips
Anchor answers in the user, a restaurant manager building next week's schedule at midnight, empathy for that moment is the product's whole point.
In design, treat labor compliance as first-class, break rules, minor restrictions, and overtime laws vary by jurisdiction and must be enforced correctly.
Show full-stack range, comfort moving between an API endpoint and the React component consuming it matches how teams here work.
Ask about the product's payroll expansion, informed interest in the roadmap lands well at product-led companies.
What they test
7shifts evaluates whether you can ship product features well, full-stack. Technical rounds use job-realistic tasks, design the API for shift swapping, model time-clock entries that must survive offline punches, build a React view over schedule data, graded on correctness, clarity, and the questions you ask. Algorithmic difficulty stays modest; product judgment, noticing that a shift swap needs manager approval and audit history, differentiates candidates.
The scheduling domain provides meaty design material. Generating a valid schedule means satisfying employee availability, role requirements per shift, labor-law constraints like minor work restrictions and mandated breaks, and budget targets simultaneously, a constraint-satisfaction problem the product tackles pragmatically. Senior candidates who discuss heuristic generation with validation layers, rather than promising perfect optimization, mirror the engineering culture's realism.
The product and the culture
7shifts serves restaurant teams, an industry with thin margins, high turnover, and managers doing administrative work between rushes. The product's expansion from scheduling into time clocking, tip management, and payroll deepens the technical stakes, payroll correctness and money movement raise the reliability bar, and integrations with POS systems like Toast and Square are core plumbing. Engineers here get genuine full-stack ownership on features restaurant workers touch daily.
Culturally the company is Saskatoon-born, remote-friendly across Canada and the US, and deliberate about humility and support as working norms, the interview's values emphasis is authentic protection of that environment. Compensation is solid Canadian-market SaaS pay, below US big-tech totals, with the offsets of real ownership, sane pace, and a product customers visibly love.
Leveling & Compensation
| Level | Title | YoE | Total Comp (USD/yr) |
|---|---|---|---|
SE | Software Engineer | 1-4 yrs | $75k - $120k |
Sr SE | Senior Software Engineer | 4-8 yrs | $100k - $155k |
Staff SE | Staff Software Engineer | 8+ yrs | $125k - $190k |
Software Engineer
Ships full-stack features with guidance, writes tested maintainable code, and grows product judgment in the domain.
Senior Software Engineer
Owns features end to end across the stack, leads design discussions, and mentors while shipping steadily.
Staff Software Engineer
Drives architecture across product areas, payroll reliability, integration platform, scheduling engine, and raises engineering standards.
How to Stand Out
Behavioral Focus Areas
Customer obsession: restaurant operators are busy, and the product must just work
Humility: a low-ego culture that screens out arrogance
Ownership: full-stack engineers carry features from idea to production
Pragmatism: right-sized solutions for a mid-size product company
Collaboration: tight product-design-engineering triads
1.
Refresh full-stack fundamentals honestly, PHP or a similar backend language, TypeScript, React patterns, and REST API design cover the technical surface.
2.
Practice practical coding, take-homes and live rounds use realistic tasks, building an endpoint, fixing a component, modeling data, over algorithms.
3.
Prepare a scheduling design answer, generating a week's schedule under availability, role, and labor-law constraints is the natural domain case.
4.
Review SQL and relational modeling, shifts, employees, locations, and time entries make classic schema questions.
5.
Learn the product context, hourly restaurant workforces, tight margins, and managers scheduling from phones, user empathy elevates every answer.
6.
Bring low-ego collaboration stories, the values rounds genuinely filter for humility and team orientation.

FAQ
Do I need PHP experience?
No, strong backend fundamentals in any language transfer, and the company supports ramping up. The backend estate is PHP with modern practices, and TypeScript spans the stack, so willingness to work in both matters more than prior PHP mileage.
How hard is the technical bar?
Practical rather than punishing, realistic coding tasks, sound data modeling, and design judgment over algorithm difficulty. Mid-level candidates with solid full-stack habits pass comfortably; seniors are differentiated by architecture thinking and product sense.
Is 7shifts remote?
Remote-friendly across Canada and the US with hubs in Saskatoon and Toronto, and interviews are fully virtual. Time-zone overlap expectations are reasonable, and the culture has invested genuinely in remote collaboration.
How does the payroll expansion affect engineering?
It raises the stakes pleasantly, money movement, tax correctness, and compliance bring bank-grade reliability needs into a product company, creating meatier technical problems than scheduling alone. Interest in that kind of correctness work is worth expressing.
