I applied through college or university. I interviewed at Efftronics Systems in Sep 2020
Interview
Asked some basic questions about electrical components and one aptitude question and a program and some questions related to company and explain the process and work and they asked about my interest in the role
Before the interview, there was a written test (pen and paper) with fill in the blanks type questions. The test was based on domain knowledge, so make sure you have a strong grip on your core subject concepts.
The questions were honestly quite tricky and unexpected — don't assume it'll be straightforward. Some questions may catch you off guard, so don't just prepare the basics. Go deeper into your domain and be ready for questions that test your understanding beyond the surface level.
