I currently work as an electrical engineer at a large company. An engineer I worked with for 1 year left the company last fall to help start a new company (approx 15 people). He recently told me they need a young electrical engineer and asked me to apply. I applied and have not heard back for 3 weeks. That seems like a long period of time to me. I understand that often times you do not hear back from employers after a job application, but I feel that since he knew me, asked me to apply, and he would be my direct supervisor that I would at least get a job interview. Should I reach out to him in some way? Any advice would be greatly appreciated. edit... it is also important to note that this position is not publicly posted, and I am unsure if they have reached out to anyone else regarding the position.
