The story is I am a mainframe(IBM) developer(but not work in IBM).
As I really want to continue to develop my skills in mainframe area, so I am thinking to chage to another company.

Now, IBM wants to move some operations(don't know the details, just some kind of applications running on some mainframe) to the IBM in my city.(IBM is everywhere, it's global, right?). And they want to make sure this transmission goes smoothly, so they need many more stuff.

Ok, here is the chance. However, they are looking for technical support rather than developer.

Actually I just had an interview with the project manager today. And he asked me if I am interested in this role since he knows I am a developer. And I tole him I am interested in that project anyway.(avoid to answer that question directly)

Since I am not quite sure what is the different between technical support and programmer, I just know I want to learn more and to develop my skills(especially in infrastructure of the IBM stuff) much further. Can you guys tell me what these two career development routine will be? And which one needs more technical skills? Hard to make decision myself. Need suggestions, so please help!

Thanks so much for any responds!

Google with the search-items "tech-support" , nightmare" , "fun" and "funny".
Spend a day reading all that stuff and decide for yourself , if you really want that job so bad.
Believe me ; Customers are worse than you can imagine.

I'd love to change career into the IT-buissness , but I consistently turned down all tech-support jobs.
I'd like to keep my sanity....

Haaha, I'm retail and I'm high up so I only talk to customers when something goes wrong but still, I hate them. They suck and your world doesn't matter to them, they're selfish and I'm just not a fan. But anyway good luck with that job

I used to work in a Job Centre call centre dealing with benefit payment complaints, none of you can moan more than me

I can - I worked front line at a JobCentre and dealt with claims. So ner-ner-ne-ner-ner

Me too, I worked at the bi*ch window at a large retail store, then got promoted to working customer service in appliances and electronics. You just haven't lived until you have a woman screeching at you about her broken refrigerator or a customer that wants to return the printer he owned for 6 years.
