Ha, one I think I'm qualified to answer, though I'm not sure I have much of use to say.
We have a lot of interns, typically every 6 months we get a new batch. My department usually gets 2-3. Most of our interns have not finished their studies yet and are also from Europe rather than USA. One of my tasks is to mentor them, I used to spend more time on it than I get to now but still…
Some are really good and get up and running in a couple of month, self starters etc, a pleasure to be around and I wish we could hire, even in lieu of some of our permanent employees. We’ve had some that after maybe 2 – 3 months are more productive than people that have been doing this for 10+ years.
Others are awful. Reasons for being awful vary. For some of them, given the fact English isn’t their native tongue this is part of the problem – those with stronger language skills tend to do better. For others it’s similar to your problem, you explain something to them several time then they either still do it wrong or come and ask you again. Others still suffer from what they are being asked to do not being something their courses really covered.
Drawing and related documentation skills are something we tend to have them do a lot of. While most of them will have had some kind of CAD training it is usually of a very basic level and concentrating on what CAD can do not what they should do with it. Certainly they have little understanding of actual ‘drawing’ or ‘detailing’ including both general comprehension of Tolerancing and actual GD&T. They usually don’t have much understanding of the documentation process etc generally. Basically, rightly or wrongly, it seems they don’t get taught a lot of the more applied, though basic, stuff at uni (this seems even more true of our few US interns than our European ones).
Some of them also have a problem doing drafting type tasks. They think they should be doing hard core number crunching (which I know some members here would agree with) and/or developing the next wave of technology, leading their own design tasks etc.
Finally, being that this is just an internship, and in a relatively exotic part of the world compared to where they come from, some of them are more interested in partying and going on day trips than working. (I have to say though, the best 3-4 interns we had were also among those that partied hardest and/or went sight seeing the most.)
As well as the 2 above extremes we have some in the middle who do Okay but aren’t exceptional.
So as Tick mentioned, does he need some more formalized training on your CAD package? This will not solve all the problems as it will again probably teach him what the CAD can do more than what he should do with it but it builds a foundation for you to then build on.
We’ve also overtime increased the structure of what we teach them etc, having a list of things they need to learn can help both sides.
I don’t know about your ECO process but at both my employers this could be fairly demanding so depending how simple an ECO or your ECO process is you may be expecting a little much. I certainly messed my first significant ECO up a little, and had it not been for the help of a more senior guy checking it/(informally) mentoring in me it would have been worse.
There can also be cultural issues, and I don’t mean just because in our case they are from a different country, but also due to generational differences etc.
After 3 months I normally have a feel for how they’ll end up, although we currently have 2 interns who’ve been here a bit longer, just over a year and I may have misjudged. Initially I wasn’t impressed by their performance, they seemed slow to get going and had the attitude that what they were doing was beneath them, one more than the over. However, overtime they’ve improved significantly and while still not at the top of my list of interns, they are probably in the top category rather than middle and certainly not bottom.
One thing to make sure is are you really telling him things 6 times or it just seems like it? We had one intern that I really struggled with. He worked really hard but just seemed to need things explained 5 times, I think a lot of it was language and some was his personality, he was Bosnian and had grown up during the troubles there and I think this had affected him, he was very nervous/uncertain. I regret to say that it got to a point where I wasn’t as patient or tolerant as I could have been and was rather short with him a few times, however part of this was perception more than reality, he probably wasn’t as bad as he seemed.
By all means I think having a review with him is a good idea, my manager routinely has review with our interns to track their progress etc. He also uses it as an opportunity to point out areas for improvement. Maybe you could tell your guy that your time is valuable so when he asks a question and you make time to answer it he needs to take notes and make sure he understood correctly by verifying what he understood etc.
Final point in my excessively long post, does he actually seem to work hard or goof off a lot?
KENAT, probably the least qualified checker you'll ever meet...
