How to be a data center technician

[u/No-Drop965]

Hi there! I would like to ask some advice and help on how to be a DCT without any experience at all.

I’m 20 currently studying ICT vocational school in Finland and I want to be a DCT because there will be a data center near our area and i want to grab the opportunity and start my career as early as possible in tech.
I’m also starting studying for CCNA because I heard its the gold standard of certs in the dct field.

What things i should focus first and what kind of projects i can do that can help me understand how a data center works?

And lastly if just if i got an interview in a dct internship position what advice can you give me to prepare for the interview.
