Application choices
Before you apply
Preparation by function
Interview preparation should start with one project you can defend in detail. Be ready to explain the initial specification, what you personally owned, the first failure, the measurement or data used to isolate the problem, the trade-off in the final design, and what you would change with another week. For a hardware or process role, expect questions that test whether you understand measurement error and physical constraints. For software, explain interfaces, tests, observability and failure handling. For business roles, explain the operating mechanism behind the number you modeled.
Work, teams and company background

Company brief and operating context
A student should read Power Integrations as a semiconductor supplier whose engineering value is tightly coupled to end-system behavior. The company does not sell a generic software platform; it sells devices and design approaches that have to work inside chargers, industrial systems, motor drives, automotive power architectures and other electrically demanding environments.
For students, the useful question is not whether the company is 'in semiconductors.' It is where the company sits in the value chain, what physical or software object the team owns, and what evidence a junior candidate can bring to that layer. The division map below is an application framework, not a promise that every function is hiring in every cycle.
Applications Engineering
Expect board-level testing, debugging, oscilloscope work, surge/EMC validation and translation of device behavior into a customer-facing engineering answer. A good student artifact is a power-converter or motor-control project with a clean test plan, measured waveforms, efficiency or transient data, and a short discussion of where the design fails.
For this role family, prepare one evidence item with a defined input, method, output and error check. State what you personally did and what depended on teammates, equipment or existing code. The goal is to make your reasoning auditable. If the project has no measured result, add a test, benchmark, comparison or post-mortem before using it as the lead application example.
Candidate fit, offer diligence and decision questions
Evaluate the internship on project ownership, manager access, technical learning, location burden, conversion path and compensation rather than employer name alone. For equipment and manufacturing employers, on-site work may be the source of learning rather than a drawback: the lab, cleanroom, factory or test floor may contain the actual problem. Conversely, relocation without housing support can materially change effective compensation. Build a simple after-tax and housing budget if the offer requires a move.
A strong offer should make the work legible. You should know the team, likely project class, manager or mentor structure, physical location, schedule, pay basis and whether the work is expected to continue after the internship. If the recruiter cannot answer those questions before acceptance, treat that uncertainty as part of the offer rather than assuming the best-case version.
Questions worth asking a recruiter or former intern
- Which team and product, process or system would own the intern?
- What deliverable did the previous intern leave behind, and was it used after the program?
- How often does the intern meet the direct manager or technical mentor?
- Which lab, factory, cleanroom, codebase, instruments or production data will be available?
- Does the stated pay exclude or include housing, relocation, transport or overtime treatment?
- Is conversion to another internship or full-time role an explicit program path or simply possible?
- What is the most common reason a technically qualified intern struggles on this team?
Product / Power Engineering
The product portfolio rewards comfort with switching power supplies, control loops, magnetics, thermal constraints, device stress and power-density trade-offs. For a candidate, a compact design review that explains component choices and worst-case conditions is stronger than an undifferentiated list of electronics coursework.
IT / Automation
The 2026 IT intern example mixed end-user support with a mandate to identify AI opportunities that could automate or improve support. Candidates should therefore show that they can diagnose systems methodically and automate repetitive work without creating fragile workflows.
Finance / Business
Historical example · 2026-09-04
Historical intern evidence includes a finance internship working with senior finance leadership. A business candidate should be able to connect semiconductor product cycles, manufacturing economics and operating decisions to revenue, gross margin, working capital and capital allocation rather than treating finance as spreadsheet mechanics.
Make the application note more than a specification list
Choose a safe academic design example, state the requirement and compare two options under consistent conditions. Identify the test that would invalidate the preferred option. Explain the trade-off in language an applications or product team could use. Keep the work within approved educational equipment and avoid unsupported claims of commercial suitability.
Hypothetical preparation exercise, not an employer assessment or a verified internship assignment.
Interview preparation
Do not memorize a generic company description. Pick one product or process area relevant to the team and form a point of view about the engineering or operating problem it solves. Then prepare questions that reveal the internship's actual quality: What deliverable is expected by the end? Who reviews the work weekly? What lab, fab, codebase or data access will the intern receive? How is a project scoped when equipment or customer dependencies slip? What happened to last year's intern project? These questions produce more decision-useful information than asking whether the culture is 'collaborative.'
Research context
Power Integrations is a power-semiconductor company centered on high-voltage integrated circuits and related technologies for efficient power conversion. Its product map spans AC-DC conversion, LED drivers, gate drivers, motor drivers and automotive power solutions. That makes the internship story unusually physical: design decisions surface in waveforms, thermal behavior, electromagnetic compatibility, efficiency and hardware reliability.
