2 small rooms each with 4-5 interviewers from various backgrounds (HR, design, manufacturing...). Interviewers were extremely friendly and casual. Total interview time took about 30mins. I advice interviewees to understand the industry and the company's operations and maybe even industry lingo (IDM, industry 4.0)
I applied online. The process took 3 weeks. I interviewed at STMicroelectronics (Singapore) in May 2017
Interview
1 to 1 interview with the Manager (Engineer). Relaxing atmosphere as the standard interviewing questions were being asked. He shared more about the nature of the job, expectation and requirement from the candidate. Being direct without beating about the bush was a plus sign; showing that what the company ones from people taking this job.
