Frequently asked questions
Is the course eligible for OPCO or CPF funding?
No. Sphinx-Digital is not Qualiopi certified and is not listed on Mon Compte Formation. The course is invoiced directly to the company or the individual, with no external funding.
What is the difference between the public (inter-company) and in-company formats?
In the public format, you join a session with participants from other companies (3 to 10 people). In-company, we run a session dedicated to your team, on your site or remotely, with content adapted to your context. In-company pricing is available on quote.
Remote or on-site: what are the practical differences?
Content and labs are identical. Remotely, labs run on cloud environments accessible from a browser, with nothing to install. On-site, you provide the workstations; labs can run in the cloud or locally depending on your infrastructure.
How many participants per session?
3 to 10 participants at most. This deliberate limit ensures everyone can ask questions, adapt the exercises to their context and get a detailed answer.
What is the evening format?
The evening format spreads the same course over 4 sessions of 3.5 hours (14 hours in total), in the evening from 6:30 pm to 10:00 pm. Same content, same labs, same price, so you can build skills without taking days off.
How does payment work?
Courses are invoiced on quote, by bank transfer. Payment in instalments is possible. We issue a training agreement for companies that want their training department to cover the cost.
