First-hand accounts from people who interviewed at onsemi.
Electrical Engineer
I had a phone screen first, then an onsite panel interview. The panel had the hiring manager and three employees, and I spoke with them one by one. It was mostly about semiconductor devices and my past experience. Chatting with the employees was great, but the hiring manager was the opposite, maybe just a bad attitude. They said I'd hear back the next week, but then they ghosted me.
- Can you explain the functioning of BJT and MOSFET transistors?
Applications Engineer
They asked questions based on my resume, so make sure you're ready to talk about your projects. The whole interview experience was pretty good, and they were flexible with the process for me. The technical questions could be on the tougher side depending on the role you're going for.
- Can you tell me about a project you worked on?
- What were some technical challenges you faced in that project and how did you overcome them?
Global Sourcing Analyst
HR asked some basic questions about leadership and collaboration. Then, the tech team asked about my past experiences, mostly focusing on logistics, supply chain, and ETL. They also wanted to know about my data cleaning experience and if I knew anything about semiconductor manufacturing.
- Can you tell me about your experience working with multiple teams simultaneously?
- Which ETL tools are you familiar with?
- Could you describe the types of data you have worked with?
Process Integration Engineer
The recruitment process was efficient and had a reasonable response time. Despite being a recent graduate and this being my first-ever interview experience, I was given the opportunity to participate in four rounds of interviews. This experience was invaluable, providing me with significant insights into the interview process. However, after completing these stages, I have not received any further communication, leading me to conclude that my application was not successful.
- Can you explain the physics behind semiconductors?
- Could you detail the manufacturing processes involved?
- What is the concentration of ions in different wafer components?
