Intel does not run one standardized company-wide loop: hiring is owned by the individual business unit or team, so the number of rounds swings from a single long technical conversation to five separate interviews. Almost every account starts with resume screening rather than an online assessment, and the interview itself leans heavily on the candidate's own projects plus CS fundamentals (C/C++, pointers and memory, OOP, operating systems, computer architecture) rather than heavy algorithm grinding, with LeetCode-style questions usually sitting at easy-to-medium difficulty. India campus hiring dominates the public record, where an on-campus resume shortlist feeds one to three technical rounds plus an HR chat; US accounts add recruiter and hiring-manager screens, phone screens and an onsite panel.
These 18 writeups cover software engineering, graphics and gpu software, ai machine learning and other roles, India campus heavy, some US. 13 of them were posted under a pseudonym (Reddit, GeeksforGeeks or forum handles), so we could not verify the authors’ identities.

Intel’s official process
In a post on Intel's own community site, an Intel staffing employee describes the shape of the process: a phone screen to assess technical skills first, and candidates who pass may be flown in for a larger onsite round of interviews. Intel recruiters on that post stress behavioral as well as technical preparation, ask candidates to bring concrete examples of leadership, teamwork, prioritization and adapting to change, to be flexible on interview dates and US locations, and note that interns are interviewed to the same bar as new grads because Intel wants to convert them. Intel's own /jobs hiring-process pages now 403 or redirect to a 404 handler for automated fetches, so this recruiter blog is the usable official statement.
One long interview split into a research-publication and M.Tech project discussion, a very long operating-systems block, and a coding block. The OS portion swept scheduling, semaphores versus mutexes, interrupts, deadlock, paging and segmentation; the coding portion stayed at linked-list and string level with hints offered freely.

Technical interview with the post-silicon validation teamTechnical
The team first checked he was willing to work outside core VLSI design, then interviewed on the areas he had been advised to prepare: Python, C and computer architecture. He cleared it and received the offer, but the internship work turned out to be tooling and scripting rather than RTL, and both his manager and team lead warned early that full-time conversion was unlikely.
Covered · Domain knowledge, Operating systems, Data structures & algorithms
A short interview in which roughly two thirds of the time went on the candidate explaining semiconductor fabrication work, drawing on his hands-on cleanroom experience at a university nanofabrication facility. He got the internship, worked on metal deposition and wafer grinding, and was later offered a full-time role with the same team.
