Great job offer but shady company?

Recruitment Scams

Before I get into my answer a quick forewarning that there is a real possibility that this is a scam. I cannot answer definitively whether this is one or not, but I cannot stress strong enough to exercise caution. The biggest red flag is if they want to charge you any kind of recruitment or hiring fee, if you encounter one of these: Run. With that said there are other types of scams out there so be alert to any and all oddities.

Ask Questions

In the professional world when you encounter something that does not make sense asking questions can reveal things that no one thought of or help reframe problems making decisions easier. In the case of interviewing, it is a two-way street, and you can and should ask them questions too.

Here are some possible questions:

• Ask about the history of the MSP, how did it come to be?
• What motivated the CEO to start this venture?
• What vision does the MSP have for their future?
• Are you their first and/or only IT person they are hiring? Which if they are only planning on having one person, then why are they looking for a junior person and not a senior?
• Will they be providing you with a company laptop to do the IT work from, or will you be expected to use your own computer?
• If they are expecting you to use your own hardware, are they planning on reimbursing you for that?

The goal of the questions is to see how well they have thought and planned out their business. If they have not thought out these type of things even if they are a legitimate company working for them would prove to be a chaotic mess.

As written - I see nothing that raises alarm belles yet.

Not everyone likes LinkedIn (I deleted my profile - too much self-agrandizing).

A Website is realistically only useful if you want to attract additional clients. I have seen setups similar to what you've described where a small business has only a handful of major clients, said clients pays all of their bills and so things like a professional looking website, extensive LinkedIn profile are not required.

If the end-company that you are going to be working for is Legit, I wouldn't be too worried at this stage.

If you have other opportunities that might look less attractive but more stable, I could understand - but the thing is - if it is full time remote and the pay comes in on time - where is your risk?

They will be providing the work equipment (and if they don't - then I consider that a red flag) and you get experience.

Edit:

Also - as per the Comments - France has a mature legal system with worker protections - so the chance of getting scammed is smaller and the options for recourse are greater.

It is unclear from your post just how far this tango has progressed.

From the outset, understand that the employer and the recruiter are not your friends, no matter how pleasing their behaviours might be. Recognise that the employer is seeking someone to do paid work for them, and the recruiter has a rolodex full of names of people just like you. It's good that you are doing your background checks and other research that you can. Kudos!

That you seem dubious about this employer/position gives you the opportunity to be somewhat aloof in this instance. (There's no hint of desperation in your post here.) In brief, let them come to you, selling the position to meet your requirements. (Apply moderation, of course.) But, if you have nothing to lose by listening to their pitches while probing corners that are not being voluntarily exposed, then you can use the opportunity to plumb your own character and limits. (Self knowledge is a virtue that you'll use throughout your career.)

Take your time and be non-committal (if you want). You may be entering a phase of your life that could extend across many years. Do you envision yourself being fairly content and making progress during that time? (A "very good salary" is no compensation if you're miserable most days earning it. You only get 1 lifetime to live.)

Further, consider your level of risk-aversion. This might be a golden opportunity, or it could crash-and-burn, at any time, for reasons beyond your control. No one can say. Gamblers have to take chances to win-or-lose on each hand. No one can tell you what you'll feel comfortable wagering in the game.

In short, you are free to turn the tables and let them fulfil your expectations. As written in the answer by @Anketam, it's a two-way street, and you've as much to gain (or lose) as the employer if things succeed or they don't. Having some misgivings are a given. Do your best to identify and seek to quell yours. You're not compelled to sign-up for a bad deal. Let them persuade you, in writing, that you're looking at a mutually-beneficial opportunity.

Important is to focus on the job and what it involves and how it might evolve over time. Do not ask about future pay rises that might benefit you. You want to be clear that you're considering doing paid work for the benefit of the employer. There'll come a time to discuss your rewards once you've demonstrated how well you fulfil the employer's requirements. (You might ask about "on-the-job" upskilling if you think you might need it. "On-the-job" means producing quality work for your employer, being "at their expense.")

(As for the recruiter, know that their bread-and-butter is to form unions. Their motivation is to sell the employer to you and to sell you to the employer. Best to take their assessments with a grain of salt. While it's true that they take some risks (refunds and/or reputation), unless you have a special relationship with a recruiter, it's best to regard them as car salespersons. They're happiest when a vehicle is driven off the lot.)
