No, it doesn't. Not being fit merely tells you that they might have lifestyle choices different from your own.
Or they might be female with PCOS. Or they might have a disease that causes fatigue or pain when they exercise. Heck, that might be the very reason for their desk job. Or a history of food insecurity and really need the insurance the job provides to be able to afford therapy, if they are even to that point. Heck, they might just not be knowledgeable enough to separate bad health advice from good health advice and despite trying things out, feel stuck. It isn't like I learned how to care for my body in school, after all. Health class focused on STDs and parts of the body while physical education classes were more focused on sports, rules, and being a good teammate.
The reality is that being overweight only tells you that they are overweight.
Quite an assumption you have there. Industrial food is cheap and crowds out normal food. Some areas are basically food deserts. A significant portion of the population also has health issues that complicate maintaining a healthy weight.
So called "food deserts" are a bit of a chicken and egg problem. Are the restaurants in your area a reflection of the eating habits of the people in that area, or a grand conspiracy to keep us unhealthy? I tend towards the former.
I am also skeptical that even in "food deserts" an enterprising individual can't acquire rice and beans.
for example, if they have recently made the decision to stop smoking cigarettes, thereby making a positive change in their lifestyle and health, this shows strength of character. it also demonstrates their ability to question past poor decisions rather than give in to the sunk cost fallacy, and then take steps to correct them. and of course, it also tends to make you put on weight [0] ... although not much more that 10 lb or 5 kg it seems, so interviewer beware, i guess ;)

I'd recommend keeping fitness a top priority especially as one gets older. Not only does everything get easier when not overweight, but the energy boost and appearance improvements certainly helps your confidence and presentation in every possible way.
I'm not someone you'd consider a "pretty" man even by a long shot, but being fit with a healthy BMI makes a world of difference nonetheless.
(I took serious stock some time not too long ago and realised weight lifting and being strong wasn't enough when actually overweight. Have dropped 15% of my body weight through dieting and the difference is amazing. I'm closer to fifty).
I've always had a hard time articulating my advice on this matter, because it's easy to be shallow, and it's insensitive because not everyone can act on it. But for those who can, it's more about being pragmatic.
It might be small things like quitting alcohol, not using smart phones until the early hours every single night - so getting enough, better quality sleep. And getting a water carbonator with the money saved from the drink, thus improving your skin through better hydration. And squeezing some walks in here and there eg by parking further away, or taking the stairs, when before you wouldn't.
Taking hard personal responsibility for your own health, I'm sure most everyone could find something to improve on.
I have a long list still to go through for myself - but I've accepted that minor transgressions one day can be balanced out by being better the next few days. Thus one can achieve balance without going crazy.
For me Intermittent Fasting has been an incredible eye opener, and weight shredder. This included learning about nutrition. On this, DIY food box deliveries (eg Everyplate, the simpler/cheaper version of Hello Fresh) are extremely high value compared to eg Uber Eats deliveries - both nutritionally, and financially. It takes effort, of course - but that's part of HTFU.
Finally, going through a process of decluttering and cleaning my home after my separation - changing these habits have been very healthy for my mental state. Perhaps this goes twice for someone with ADHD, like myself. When I'm home now, I truly feel at peace; it's changed my attitude into a more positive one, which has improved my energy and clarity of thinking.
It's all about habits, and mental and physical health interconnect; maintaining both certainly takes discipline and effort. The effects are observable, though, and everyone judges everything all the time on an unconscious level. Fair or not - as biological beings that's just how it is.
