What are the options for organizing this workshop? What's the optimal/maximum group size per workshop?

For each workshop, we have a few options available:

Private in-company workshop - the trainer conducts the training at your company, exclusively for your employees. The optimal group size is around 15 people, but the workshops are effective for up to 20 people.
Private online workshop - the trainer conducts the training online, exclusively for your employees. The optimal group size is around 15-20 people, but we can accept bigger groups.
Open online workshop - the trainer conducts the training online, and anyone can join. You can join one of the planned editions, or you can request a new one, especially if you already have a group of people interested in the workshop. We close registration when we have 20 people.

Which option is better: in-company or online? What are the costs?

Both options have their pros and cons. The in-company training is considered more efficient, however, organizing can be harder, especially if developers work remotely from different locations. If you decide on this option and the workshop is organized outside Warsaw we will add an extra cost of travel and accommodation of the trainer (around 1000 EUR but this will vary depending on the location and length of the workshop). For the online training version, no additional costs apply as it is conducted on Zoom or other platform. It might be more convenient for developers, and certainly easier to organize.

How does the structure of this workshop look?

The structure of all our workshops is similar. Every block starts with a theory, that includes a presentation, discussions, challenges, and Q&A. After that, we have a practical exercise, where you can practice what you have learned. Attendees are encouraged to ask questions and participate in discussions. There are many smaller or bigger challenges, appropriate for the section and the level of the group.
