LinkedIn does not publish the format. Each row is what candidates and prep guides have described publicly, with its source; where sources disagree, the row says so. Formats change — treat every specific as reported, not official.
| Roles | Data Analytics, Data Science and Data Engineering.[4] |
|---|---|
| Data analyst loop | Recruiter screen, hiring-manager conversation, then a same-day final loop of two to three hours (technical, culture, stakeholder). The technical round uses a shared editor or SQL tool with two or three small business tables.[1] |
| Data science loop | Recruiter, hiring manager, one or two technical screens of 45–60 minutes that pair SQL with a case or statistics, then a loop of four or five rounds. In one 2026 catalogue of 58 questions, about 17% were data manipulation in SQL or Python.[2] |
| Emphasis | Fundamentals rather than advanced techniques; one staff-level report describes SQL as a small part of one onsite round.[1][3] |

Our LinkedIn practice set, by skill
The 16 SQL Quest challenges tagged LinkedIn, resolved onto the nine Skillmap skills. A challenge exercises several skills, so shares do not sum to 100%. This is the composition of the practice set on this page, not a measurement of LinkedIn’s interview.

Our challenges, chosen because their SQL matches the shapes above; not questions LinkedIn has asked. Each card opens the challenge in the browser — no signup.
Skillmap
Ten questions, no signup. You get a readiness score weighted to the SQL this page covers, your Skillmap across joins, window functions, aggregation and the rest, and the weakest skill to practise first.
Drill the skills the LinkedIn set leans on, one at a time: GROUP BY exercises · JOIN practice · CTE practice · Window function practice · NULL handling practice — or browse every SQL practice question.
Every question in the LinkedIn set, one page each with the schema and a hint: High-Volume Categories (HAVING) · Rank Everyone by Salary · JOIN with a Filter · LEFT JOIN: Watch the NULLs Appear · Filter on an Average You Just Computed · LEFT JOIN: Keep Everyone · GROUP BY + HAVING · Self-Join: Employee and Manager · Multi-Month Active Customers · Earning More Than the Boss (Self Join) · Genre-Spanning Directors (HAVING) · Top 3 Salary Tiers (DENSE_RANK) · Salary Rank Within Department · Employees Earning More Than Manager · Anti-Join Pipeline: Unmatched Records · Customers with Orders in ALL Categories.
