Question

Career in IT

Good afternoon.
Prehistory.
I don’t know how, but one day I was sorting out the spam in the box, I came across this thread Interview, questions for the position of L3 Technical Support Engineer?

Main convoy.
For me, the end admin support is people who install, change, update, etc. in general, do support.
And what are their prospects? Maybe I have a biased perception. And in general there were questions:

the questions themselves.
1. I never thought about it and wondered what are the prospects if you get a job like this support engineer L / 0/1/2/3?
2. Where and what can you grow into if you work for some well, for example, HPe. And what are their interview questions?
3. Who needs these engineers after all there IBM, HPe, NEtapp, Hitachi, Dell, etc.?
After all, they are very narrow-minded.

Answer 1

I never thought about it and wondered what are the prospects if you get a job like this support engineer L / 0/1/2/3

Well, you will become a super-duper engineer for a certain technology, you will communicate with other L3 engineers in another technology.

Where and what can you grow into if you work for some well, for example, HPe. And what are their interview questions?

This is experience and methodology. You can get a job with someone who actively uses the HP infrastructure. You can easily retrain to another manufacturer (only the names and some features change, the meaning of the operation remains the same, what difference does it make - Cisco or juniper, if you understand how bgp works by heart).

Who needs these engineers after all sorts of IBM, HPe, NEtapp, Hitachi, Dell, etc.?
After all, they are very narrow-minded.

Starting from some career moment, any person chooses where to grow: in depth, up, in breadth, or even change the technical direction to a commercial one. This is about any profession, not just support. You can become a super-duper HP firmware specialist, or you can become a technical support manager.

Answer 2

1. I never thought about it and wondered what are the prospects if you get a job like this support engineer L / 0/1/2/3?

The question is wrong. These are not different levels of the same profession, these are generally different areas and responsibilities in the SDLC. The movement of a specialist between these levels is not up, it is sideways.

2. Where and what can you grow into if you work for some well, for example, HPe. And what are their interview questions?

Judging by your questions, I have a counter question. Can you imagine a company like HP? Or at least the number of referrals they have?
Do you want a support engineer for refilling HP cartridges? Or repairing HP office printers? Or repairing HP industrial printers? Or service warranty on hard drives? Or developing device drivers? Or server support?
Can you imagine that an HP engineer has thousands of different jobs with different requirements?

3. Who needs these engineers after all there IBM, HPe, NEtapp, Hitachi, Dell, etc.?

A large company has many engineers. Not all of them are high-level mega-specialists, and due to the brand, the company can afford to pay below the market. While heaps of other companies may pay more, it's natural for experienced people.
