How terrible of an idea would that be if I just run Logit model and explain the coeffs as the first pass of a causal project?

How terrible of an idea would that be if I just run Logit model and explain the coeffs as the first pass of a causal project?

Tldr: is fitting a Logit model on observational data and explaining the coefficients in the causal manner a terrible idea assuming the X variables aren't too crazy.

So, for context. The goal is to understand what causes store promotions work - which are driven in big part by how the executions go: perfect execution - great result vice versa. The goal is not really to tease out the influence of macro drivers on demand or micro customer level factors either. It's mostly to pin point operational breaking points and quantity them.

To learn about the operational breaking points we don't need any causal model just pure data exploration is good enough. But manager has been pushing to deliver some kind of model based analysis to provide what causes an initiative produce result. He comes from non DS background and from what I gather he just want to have some brownies points saying we ran some DS models to come up with numbers.

So with that in the background, would that be a too terrible idea to just run plain LR on the observational data and explain the coeffs like they mean causality while they don't actually and the model is riddled with tons of biases that we can point out?

Last step in a company’s vetting process is a “project”… where to draw the line?

Last step in a company’s vetting process is a “project”… where to draw the line?

Update at the end.

I’m in the late stages of interviewing at a manufacturing company to work as a market/growth analyst. This would be my first DS role out of grad school and I’ve experienced firsthand how garbage the job market is right now.

That said, I’ve been told that the penultimate/last stage of their process is some sort of project. I honestly don’t remember entirely what the HR person told me, but something about getting 24 hours to accomplish some sort of task at the company. The interview process has already been somewhat involved, with progressively longer on-site meetings with more and more people. The job itself is 100% in-person and I’m not super excited about it, but a job is a job and right now this seems my best shot at being employed in the field.

Anyway, I’m leery of whatever this “project” is because it sounds like it could potentially be really time-consuming and basically me just doing free work for the company. Like I said, it’s hard for me to make a judgement since I don’t know all the details, so it could very well be a “here’s some data, see what you can do with it” kind of situation instead of a “we have this specific thing we need you to for us and we’re timing you.” I think the recruiter might’ve said something about it being paid, but if it is I bet it’s closer to minimum wage than not.

What would be a good approach to evaluating whether the project is reasonable or not? And would it be bad if I tried bringing it up in the current stage I’m in, asking them what they hope to accomplish by having me do a project and how it’s meant to contribute to determining my overall suitability for the role? I don’t know how set in stone this step of their hiring process is, or if it’s meant to be a surrogate for the equivalent of a technical interview or what.

TIA!

Edit:

Officially on to the "project" stage of the process. Supposedly the last step and waiting to receive an email with instructions and info. However! I did some more gleaning online and I'm seeing people who interviewed previously at this company say it was a 40 hour "Business Simulation"... So, big yikes. Doesn't look like I can afford to decline right now, but good God, what overkill. I don't know what they hope to accomplish and I suspect this is their substitute for a technical interview because, quite frankly, I don't think there's anyone there qualified to give me a technical interview since I'm applying for the first real role in data. I was going to continue looking for better options and trying to interview elsewhere even if I got this job, but I'm definitely going to now....
