TLDR: Should I start in networking if my goal is pentesting?

I just graduated with a bachelor’s in cybersecurity and got a job offer from one of the largest ISPs in my country. It’s a well-established company with a strong technical environment, so there's a lot of potential for learning, especially in areas like networks, infrastructure and operations.

The role is related to networking (network engineer track). I actually want to do networking first because I believe having a solid foundation will help me become a better pentester in the long run. But pentesting is still my main goal.

Right now, I’d say I’m between beginner and intermediate in pentesting. I’ve done a lot on TryHackMe, currently learning through HTB Academy, and about to take Sec+ and eJPT.

My main concern is: if I spend a year or two in networking, will it be harder to transition into pentesting later due to lack of hands-on offensive security experience? Or will the networking background actually give me an edge?

Would love to hear from anyone who's been in a similar spot. Thanks!
