Where I am now we're not expected to bill quite as much for this reason. Although I did once work somewhere where there was a requirement for 2250 hours/year billed. Which doesn't seem *to* bad until you take PTO into account and the aforementioned bio breaks.
That being said, I don't worry about tracking bathroom breaks, or the occasional mental break here and there. My client is happy, I'm getting done what they're wanting to get done when they're wanting it to be done, I just bill 8 hours for the day and it's not a big deal (obviously it isn't, they've been willing to pay for me for almost three years at this point on two different projects and I get glowing reviews whenever I request feedback from them to pass along to my boss).
I work 8:30 to 5:30 so that includes an extra hour for lunch, by the way, so that's not counted, no. But I'm at home, so it doesn't feel like work anyway, just an hour to relax, have a sandwich, let the dogs out, and maybe throw a recipe in the slow cooker for dinner.
I'm actually in the middle of a 3.5 week break because I had so much built up time at the end of the year. I knew my client does a two week furlough for consultants at the end of the year so I was already planning for that, and also was planning a week for a wedding trip for a wedding ceremony/reception that had to be cancelled because a recent hurricane pretty much destroyed the town it was going to be held in. And I took a week off for vacation earlier this year.
At least in my case, the quality of my work as a consultant is no worse than any work I've done in industry (and almost certainly better, as I got exposed to more modern practices and worked with a wider variety of people), and I had industry jobs for like 16 years before this job.
My client also requires code reviews with engineers that work for the company internally (technically just other people on the team, but there's a couple internal people on the team that usually do the reviewing), so pretty much everything I write gets internal approval before it gets merged into the codebase.
If I got questioned about that in the interview, I could just tell them that.
Also because my firm is smaller they might not realize it's a consulting firm to begin with just from the name on the resume. It isn't something easily recognizable like Deloitte or Accenture.
It's definitely true for some people I've met, but it's definitely *not* true for others I've met. But if you're interviewing, how does the potential employer know which you are?
I really appreciate my consulting experience just from the sheer diversity of cloud environments and languages I've had to deal with but who knows!
I've been mostly getting away with just over 40 hour weeks, although if I was on any other client at the company I'd be expected to bill 45 hours. PTO is very flexible as long as I'm meeting my utilization for the year (working 85% of potential hours) and can get approval from the client (which for me hasn't been an issue). Even the year where I was a bit under my utilization due to no fault of my own (they didn't have me staffed on a client for six weeks so I wasn't billing anything and then when they finally did at first I could only bill 10-20 hours a week) it didn't stop them promoting me that year and giving me a pretty decent bonus.
Also the only job I've ever had where I can expect an annual bonus worth a damn. I had one for one other job briefly but it was small and they took all bonuses away after two years to save money.
They do encourage working extra hours on internal initiatives and things like that, but I mostly haven't and it hasn't hurt much (maybe I get a slightly somewhat lower bonus and I'm getting promoted a bit slower).
While there's a lot of younger people at the firm, there's several older engineers here too, including a few guys in their 50s.
I'm also like 99% WFH. I go into the office every once in a while for quarterly parties or for some important in-person event, but otherwise I'm fully WFH. Which has been especially important this year as I've been having some issues with my legs and have had to have several medical procedures on them and work on the couch a lot to keep them elevated.
I don't think I could work for one of the Big 4, though, those sound completely exhausting. I hear 60+ hour weeks is often the minumum expectation there. I've got a life outside of work, including games I'm coding in my spare time, I don't need that shit.
