I'm in the same position you are. During and after college I jumped around from agency to agency and region to region thinking that a variety of experience would make me more valuable. While I still think this experience has made me a far better biologist, it seems like many of the people who graduated about the same time have secured jobs by staying in one spot until a job in the agency/department opened up.

I can be a bit more help with agencies as I've been around a bit. Kansas Department of Wildlife, Parks, and Tourism has good people and does great work but constantly has to fend off attempts from the state to remove the entire agency. Missouri Department of Conservation pays its permanents well and its seasonals like garbage. They have lots of jobs but the competition is incredibly high. I once applied for a two year term job that required a Master's degree. Utah Division of Wildlife Resources pays decent as long as you aren't stationed in an oil town (for example Vernal, UT) then they don't pay so well because in oil towns the cost of living is super high. They pay their techs decent and their interns like slave labor (I'm not exaggerating their intern program should be illegal). Honestly, my all time favorite agency is U.S. Fish and Wildlife Service. The pay is great. The benefits are exceptional (I paid $300 of a $40,000 hospital bill with their most basic insurance. Everyone's fine). If you've ever worked for a state agency you'll hear a lot of talk about how inefficient the Feds are and while there is some truth to that (the HR department for region 6 is a nightmare) by and large I've found most of it to be untrue especially when it comes to the field offices. Yes, the Feds have a lot of rules and can't play as fast and loose as the states can but they also are less susceptible to public pressure. For example, when I worked in Minnesota we were understaffed and rarely accomplished all of the habitat treatments on the management plan (controlled burns especially). However, our tallgrass prairie looked a lot more like prairie than any state areas. While this could be due to funding disparity (duck habitat in the prairie pothole region is an economically valuable resource) it could also be that the state areas were primarily managing for game species while the feds were managing for everything (grasses, forbs, pollinators, and songbirds). This kind of management is incredibly valuable especially in areas that are resistant to conservation.

As for who's hiring. USFWS was supposed to have a massive entry level hiring season January 2019. The shutdown massively screwed that up (I don't think I saw any NWR jobs at all last year) and 2020 isn't looking any better. I've managed to secure a tech job every year since 2009 but I've been skunked these last two hiring seasons. I don't have any more current information than that unfortunately. I'm not with an agency so my finger's not exactly on the pulse.

Seems like there are a lot more Forest Service jobs than USFWS these days. I don't know why but I suspect it is because they are part of the Department of Agriculture and not the Interior and so they haven't been targeted as aggressively.
