Our career services director gave us access as part of a university program. I liked that it wasn’t just a question bank; you actually record yourself answering and get a score. It helped me prep for a consulting interview and I ended up getting the offer.

That lead angle trick is good for waterjets, but it's not the only way. On my old band saw with a diamond blade, a straight cut with the right feed pressure works better for those curves. Tilting the head on that setup would just bind the blade and ruin the piece. Different tools need different fixes.

Tell him to come over and watch me "waste" it on frozen pizza rolls next. Honestly, the thing gets used for reheating leftover fries more than anything fancy. If I'm not burning frozen food in there, it just collects dust.

Cheap tools always fail when you need them most, just like everything else these days.

Honestly, that whole story is such a good example of how the simple fix is often the best one. Modern solutions can overcomplicate things that old hands already figured out.
