I am finishing up my degree at my university within the next 6 months. I've been starting to apply for all sorts of jobs in which I may remotely be interested. For example, there are a lot of jobs I'm interested in at Google. I always make sure I meet the minimum requirements for these jobs, but oftentimes I'm nowhere near the preferred requirements.
What positive and negative side effects can I expect from applying for a lot of jobs within the same company?
When the Google form says they think your work shows them enough about you, i.e. a cover letter is not required, do they mean it? Or do they secretly want a cover letter and they're trying to weed out people who don't submit one?
How long does a Google job posting typically stay up for?
