Today I learned about....batteries

Very interesting. What would you be doing if you got hired there? Good luck!

I was told that they are hurting for engineers in a bad way, and I might do Big Problems, or Little Problems.

Either way, I doubt I'll get a call back, which is fine because I just started a new job elsewhere. I went on the interview because I wanted to learn about batteries, and ended up really really liking the company.

I've been told there are only two or three battery manufacturers for auto/ lead batteries in the US. I cannot imagine working in a battery plant

Out on the floor, honestly, looked tough. Some people wearing these hazmat type hoods, lots of fumes. Some parts of the plant have wet floors and you can kiss your pants below the knees goodbye. Plus the regular blood draws and job reassignments if you test results come back high (OSHA limits are 30 somethings per CC, this company removes you from the exposure if you hit 14, until your body clears it).
And I learned that your body clears lead over time.

If you ever meet someone that works in a battery plant, buy 'em a drink and say thanks. Most of our cars simply wouldn't run without those people, and that's a rough job, even in modern times.
