Recently I was approach by a recruiter from a company about a position that was similar to mine. I wasn't openly looking but wanted to see what they had to offer. Best jobs are usually when you aren't looking.

Doing my research on the company and position from web searching then asking the recruiter questions. it showed it could be a great opportunity. It was way bigger network and had linear path of NOC L1, L2 either Network Engineer / Network architect. This is what I've been trying to get into! Where I am now we have one network engineer who is CCIE level and not going to go anywhere anything soon. Add in fact I never get to shadow work with him due to different locations. From LinkedIn stalking the people at this other company consisted of two NOC teams with a third being built, almost everyone had a solid network background and tenure at the company an average of 5 - 10 years.
Interview / Offer
Went through the hoops they had with phone interview, tech phone interview and then a in person (8 person btw! That was a beating). I get positive feed back from in the personal interview and get the offer... way lower than I expected and position title changed. Instead of the L2 position its a L1 now.
Background and Offer pay
Current - L2 NOC Engineer recently promoted. L1 pay was 55k with 10% bonus (60k). L2 position where I am now is 65k with 10% bonus (~71k).
Offer - L1 NOC engineer 56k with 2.8k sign on bonus. With in a year if I didn't get a pay raise it would be back to 9k cut. Kinda a gamble. Maybe I can score a promotion and pay raise maybe not.
The position I have now actually worked that way as well. Interviewed for a L2 but got offered a L1. I climbed my way up after a year recently. The position the other company offered was actually more than I made as a L1 here with a sign on bonus. (I do consider bonus pay when asked full compensation however bonuses don't mean anything to me til its in my bank account)
So when I think about it. It does sound like a big cut. But since I just recently moved up I'm not even use to the increase. I haven't even gotten a months worth of new pay. Question is...do I make a lateral move and start where I was or sit where I am now. I feel like I can get experience here but at a slow rate compared to other job where I would almost be running.
I'm not a compensation chasing person. I look for opportunities more than $$$. However, I'm afraid of feeling of starting over again.
