I will add my two cents for people who believe that this might be related only to the SWE and tangent industries: It's really not. I have many friends (in Europe) who are trying to get through to different jobs in unrelated industries ranging from finance to fashion, or just trying to get promoted vertically (or horizontally), failing rather miserably. Most jobs are now hoops after hoops, not taking into consideratio…
Incidentally, I read a post today which swore that the only way to get hired is NOT to rely on network. Because hiring managers receive so many applications if you don't get your app in the first 24 hours it's guaranteed to be rejected. I think the network thing works only for smaller companies.
Employee: “Hello, hiring manager. I know an incredible candidate for that job we posted last week.”
Hiring manager: “Thanks, employee, but we have hundreds of resumes from strangers, so we don’t need to talk to your contact.”
I’m not saying that never happens? But I am saying that it happens rarely enough that you shouldn’t use it to guide your networking strategy.
