Common questions

How many Software Engineer interview questions does Shopify actually ask?

It varies by round — phone screen typically covers 5–8 questions, on-site loops cover 15–25 across multiple interviewers. The full Shopify Software Engineer loop tends to surface 30+ distinct prompt patterns, which is what we've banked here.

Are these questions actually asked at Shopify?

Yes — every question on this page is verified, meaning at least one candidate reported being asked it in a real Shopify interview. We don't pad the list with generic prompts that weren't reported.

What's the best way to prepare for a Software Engineer interview at Shopify?

Pick three to five of the questions below in your weakest archetype, run them through the practice tool out loud, and read the per-answer feedback. Most candidates who get an offer report 8–15 practice sessions in the two weeks before the interview.

Does Shopify ask different questions for different Software Engineer levels?

The behavioral questions stay roughly the same; what changes is the bar on the answer. At more senior levels, Shopify expects more concrete business outcomes, more stakeholder management, and more scope in the stories. The technical bar also shifts upward.
