Most-reported questions and how to practice them
21 coding questions reported by candidates for Intel, sorted by how often they were reported. Source: community-sourced LeetCode company lists.
Of the 21 questions reported for Intel, 62% are medium, 5% are hard and 33% are easy. The most reported are Two Sum, Find Consecutive Integers from a Data Stream, Maximum Nesting Depth of the Parentheses, Valid Parentheses, Copy List with Random Pointer.
This list comes from community-sourced LeetCode company lists. It covers coding questions only. It does not tell us how many rounds Intel runs, what each round covers, or what it pays, and those change by role, level and team, so we do not list them. Ask your recruiter what each round covers, and check the company's careers page.
Prepare for the rest of the loop with the coding interview patterns guide, the system design framework, and the STAR method guide. Written by Kieron.

Start with the 21 most reported Intel questions, then work down the list.
Mediums are the bulk of the list (62%), so spend most of your time there.
Time yourself: 20 to 30 minutes per medium, then explain your solution out loud as if to an interviewer.
After each problem write down the pattern and the signal that revealed it. Patterns transfer to problems you have not seen.
Pair coding practice with a system design framework and prepared behavioral stories; most loops include more than coding.
Practice answering out loud with an AI interviewer built from your resume and the job description, and get a score and specific fixes for each answer. We are not affiliated with Intel, and the mock interview is general practice rather than a simulation of Intel's own format.
Run a free mock interview from your resume and see where your answers need work.
