I’m not a senior, but I do have more than twelve years in th IT field, various positions, jobs and employers.
I think everyday you should learn something and in this field particularly you should be able be always learning. I think you need to be open-minded. This is a key concept.
In my opinion all IT pro’s should be thirsty of knowledge, know how to do things, do them well and have critical mind to improve them .
There are not many opportunities to be contracted to work at a NOC and even less to be trained when you have little or no knowledge regarding the technology you’ll be using.
If I were you, I will go for it.
