Why Internships Changed the Way I See Engineering?
Ask someone to describe an engineer and you'll usually get the same picture: lab coat, some machine humming in the background, maybe a person hunched over CAD software drawing up a part. Honestly, I had that picture too, right up until I actually stood on a factory floor and realised I didn't have a clue what engineers actually did with their day. I'd always liked pulling things apart to see how they worked, but that turned out to be maybe five percent of the actual job.
I was seventeen when I started interning, years earlier than most people get any real exposure to the field. Since then I've put in over 300 hours across a mix of industries that don't have much in common on the surface: power transmission, defence manufacturing, turbines, aluminium die casting. Each one ran completely differently, and honestly, each place chipped away at some assumption I didn't even realise I was carrying around.
If there's one thing that stuck with me above everything else, it's this. The finished product is almost the least interesting part of engineering. It's everything invisible before it that actually matters, decisions nobody ever sees, one person quietly handing something off to the next without anyone outside the process noticing. I used to size up a product purely by how it looked once it was done. Now I catch myself wondering about the entire mess it went through just to get there.
JK Fenner was where it started. I walked in picturing myself watching machines hum along for a few weeks. Instead, I found out that a huge amount of the real work happens before a single machine even switches on. Plenty of companies, I learned, don't build every part themselves — they source from specialized suppliers and then put those parts through serious scrutiny before anything gets stamped with their name. It rewired how I thought about manufacturing entirely. Procurement, logistics, inspection, the whole business of earning a customer's trust, none of it is background noise. It's as central to the job as the machining itself.
Then came Blue Horizon Defence Systems, which felt like stepping into an entirely different atmosphere. You could sense the difference within seconds of walking in — stricter procedures, limited access, a kind of seriousness that hung over everything. I watched engineers assemble and test the Naval Surface Gun (NSG) and the Range Extension Kit (REK). Most of it I could only observe — you don't get hands-on with defence hardware as an intern, for reasons that don't need explaining. Still, standing back and watching taught me things no classroom could have. Every measurement got double-checked. Nobody rushed. Nothing was taken on faith. That's where I really understood that precision isn't a nice-to-have in this field, it's the difference between something working and something failing at the worst possible moment. A tolerance that's slightly off isn't a cosmetic issue here; it's a safety one.
Turbine manufacturing was next, and up until then, turbines had only ever been diagrams in a textbook to me. Watching the actual components come together, and grasping just how unforgiving the tolerances were, taught me something textbooks never could. I saw engineers measuring differences most people would never even notice, and I watched Quality Control operate almost like a checkpoint nothing could sneak past without meeting spec exactly.
Somewhere during all this, I also picked up the ability to actually read a technical drawing, which turned out to matter more than I expected. The first one I looked at was just noise to me, lines, symbols, numbers with no obvious logic. By the time I left, I could follow one start to finish, and there was a real sense of accomplishment in realising I'd picked up a language the engineers around me used without even thinking about it.
I also got hands-on exposure to different manufacturing processes, milling, threading, boring, grinding, machining. What stood out was how deliberate the choice of process always was. None of it is arbitrary. You pick milling over grinding, or boring over threading, because the material calls for it, or the design won't tolerate anything looser, or the part just has to hold up a certain way once it's out in the world. There's always a reason, even when you can't see it just by looking at the finished piece.
My most recent stretch was at Tyche Diecast Pvt. Ltd., learning aluminium pressure die casting, and this one genuinely caught me off guard. Things that look effortless from the outside almost never are. I watched molten aluminium get injected into precision dies under intense pressure, producing parts that would later be machined, inspected, and sent off to automotive, defence, and general engineering clients. What impressed me wasn't the process itself so much as the consistency behind it. Producing one great part isn't hard. Producing the thousandth part identical to the first, that's the real test.
The more time I spent on these floors, the more it stopped feeling like any one person's brilliance was driving things. It's a team of people leaning on each other, designers, machine operators, quality inspectors, production engineers, supervisors, and the second one of them drops their piece, everybody else feels it immediately. I started noticing how much of the job actually comes down to just talking to people properly, not just knowing your own corner of it. Some days that mattered more than the technical stuff did. Every internship left its own mark. One taught me how quality control quietly builds a company's reputation. Another showed me what responsibility actually looks like when the stakes are real. Another handed me precision engineering and the ability to read a drawing the way you'd read a sentence. The last one opened my eyes to what large-scale production actually demands.
But the real change wasn't any single lesson, it was how I started thinking altogether. I don't picture "designing machines" anymore when I think about engineering. I picture the actual mess of it, a problem that doesn't have a clean answer yet, a judgment call nobody can make for you, people who don't think the way you do but whose piece of the work you still depend on. Nothing ever feels quite finished, and I've stopped expecting it to. The thing that actually got to me was watching engineers who'd clearly been doing this for twenty, thirty years, and they'd still stop mid-task to ask a dumb question out loud, still go back and check a number they'd already checked twice, still fiddle with some process they'd run a hundred times just because they had a hunch there was a slightly better way to do it. I genuinely don't know if that itch ever goes away with experience. Part of me hopes it doesn't.
Most people don't get this kind of exposure until university, if they get it at all. I know how rare it's been to start this early. These internships gave me more than technical skills, they gave me a feel for what being an engineer actually is, from the inside looking out.
