Shopify Interview Experiences

A/B testing setup and how to handle p hacking and peeking at results came up and I wasn't expecting that at all. First technical round was statistics and probability, questions about distributions and how you'd design an experiment with finite sample size constraints. Second round was a machine learning system design question about building a merchant recommendation engine at Shopify scale. Also a values interview that felt more human than most. Long process overall but the interviewers were smart and treated it like a real technical conversation rather than a gatekeeping exercise.

Portfolio review first where they went through three of my case studies in detail, pushing on why I made specific decisions at each interaction point. Then a design challenge about improving onboarding for new Shopify merchants, 45 minutes to sketch out a user flow and present it. The interviewer pushed on the reasoning behind every design decision, intense but good practice. Then a values interview which felt like a genuine conversation about what you care about and how you work, not a box checking exercise. The whole thing was about 3 hours across two sessions. Shopify design interviews are different from what I'd done elsewhere.

80 min HackerRank with 2 programming problems and MCQs on data structures, algorithms, OS and networking. OS questions covered process scheduling and memory management, pretty niche second year stuff.

Online assessment first with situational judgment and pattern recognition and logical reasoning stuff. If you pass that you get a 1 on 1 interview with 4 behavioral and 2 situational questions. Then the panel, 6-7 behavioral questions in one hour using the CAR format not STAR. A lot of questions one after another in a short window.

Design a feature for the Shopify merchant dashboard and root cause a metrics problem, also some systems design questions which apparently Shopify dev interviews are way more product focused than other companies.

Portfolio review where we did a collaborative problem solving duet thing with a designer, that was fun then the life story interview which is them asking about your life and how you got to where you are

Process took 3 weeks they were slow to schedule next rounds but the people I met with were all friendly. Questions like walk me through this block of JavaScript and CSS nothing I haven't seen before but be careful about very specific syntax.

Was expecting heavy technicals going into the first round but really just SQL queries and theory about how you would go about implementing some APIs for financial data was surprised there was no live coding.

interview was hard, questions were annoying , and kepy interupting

Low level design, pretty easy. search lld questions on youtube
