Pluspunten
All projects are at most cases identical to each other, so you will probably be doing the same tasks over and over on different projects, so your only actual problem will be time management. If you get the hang of it and after you notice that most people expected to guide you have little idea on how to do their job, you will relax and take your time. Noone will bother you unless it's 2 days after deadline.
Minpunten
Since all managers and the CEO focus on meetings rather than actual work, be ready to receive minimal support and/or guidance, meaning you will learn as you go, while they expect that you instantly deliver, even without any real onboarding. Most probably, because there is zero understanding of basic PM principles, you will be asked and tasked to deliver on extra projects you have no idea about, while being yelled at like you're the one paid to manage. Also, the total lack of time management skills will definitely be a burden, because they forget to monitor deadlines, but expect you to deliver tasks, no matter how big or small, in the last minute and in the best shape.
Salary-wise not only is pay significantly below market-average but it will definitely not correspond to the quantity and variety of tasks assigned, givent the fact that there is a definite lack of interest and/or negligence on employee growth, career path provision etc.
All in all, if you want to get your first 6-month or 1-year experience, you can possibly consider this company, but expect to come across a toxic and heavily disorganized environment where doing more for less is viewed as normal.
