1. Guide to Researching a Company Pre-
Interview:
1. Sniff Out the Financial Health
Once you have this information, it’s up to you to draw your own
conclusions. While you don’t necessarily want to spout off stock
prices or funding history, being able to speak insightfully about
where you think the company will go in the future, backed up
with facts, is hugely impressive in an interview.
2. Watch Community Interaction
Somewhere along the application process, someone you’re
interviewing with has likely Googled you and scoured your social
media accounts. You should return the favor by finding out what
the company has been up to lately.
Aside from the news that comes up when you Google the
company (which you should also read), corporate blogs are gold
mines, especially for younger companies that are growing.
Whether it’s a post welcoming new staffers to the sales team or
detailing new features of a recent software update, this is the kind
of stuff you should know about.
3. Noticed Community Interaction
LinkedIn is also a good tool for learning about what kind of news

2. the company communicates—and therefore wants you to know.
Check the company page on LinkedIn and see what kind of
updates are featured. Is there a promotion for Mother’s Day, or a
statement on how the sales team exceeded earning expectations?
Either way, this will show you what types of things to bring up in
conversation. (Oh, and while you’re on LinkedIn, check out the
profiles of the people you’ll be interviewing with. Make sure you
have your profile set so that they can see that you’ve viewed their
profiles. This might seem counterintuitive, but it actually shows
that you care and are doing your due diligence before the
interview.)
