Candidates describe the Qualcomm software engineer interview as broad rather than algorithmically deep. The most repeated theme is the resume: several report being asked to explain projects, tech stack choices and what they actually built in detail, so be ready to defend every line of your resume before worrying about hard puzzles.
Technical questions are usually described as basic to moderate. Candidates mention OOP concepts, core Java topics such as the Java 8 stream API, method overloading and garbage collection, SQL and query optimization, and hash map versus hash set. Coding prompts reported include arrays, strings, hash maps, checking whether a number is prime, palindrome and Fibonacci-style problems, longest common subsequence and 1-D DP. One report describes an online aptitude and coding assessment beforehand, and several mention an HR round covering fit, salary or shift availability.
Focus varies by team. One candidate reported C, RTOS, pointers, bitfields and a question on how an operating system runs a process larger than available RAM. Another reported electronics questions such as power amplifier classes and sampling, and another saw identity topics such as SAML, OAuth and OIDC. One screen reportedly covered only OOP in C# over about 25 minutes. Outcomes are mixed, with both offers and rejections, so practise explaining fundamentals cleanly under pressure, review the stack named in your job description, and be ready to talk about your strengths and how you handle unfamiliar situations.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports an online aptitude test and coding assessment before the interviews. Not every candidate mentions this step, so it may depend on the team or hiring channel.
Some candidates describe a short phone or Teams screen. One Teams screen lasted about 25 minutes and covered OOP concepts in C# plus a question about strong points. Another phone screen focused on background and role fit. Others report going straight to a technical round.
Candidates typically describe this as the main round. It combines simple coding on arrays, strings, hash maps, DP or linked lists with questions on Java, SQL, OOP and DBMS. Several say interviewers dug into resume projects and technology choices. Depth varies by team: some reports include systems topics like RTOS, pointers or memory limits, and one mentions a panel of three interviewers.
Some candidates report a managerial round focused on past projects and the soft skills listed on their resume. Candidates should be ready to explain what they personally built and why.
Several candidates report a final HR conversation. It is described as fairly standard, covering background, fit, salary or shift availability. Some reports end with offers and others with rejections after earlier rounds, so the HR step is not necessarily reached.
