Capgemini offer

Hi Everyone, I have recently received an offer from Capgemini, and I have a few questions. If anyone has idea, I would really appreciate your help.

1. Offer Acceptance and Legal Concerns: The offer has an acceptance window of 15 days. If I accept the offer and later receive a better opportunity from another organization, would I face any legal issues if I decide to join the other company? I am required to submit a signed copy of the offer letter upon acceptance.

2. Project Assignment: After joining Capgemini, is it likely that I will be placed on a bench, or will I be directly assigned to a project? Will there be a client interview before joining to ensure a direct project assignment?

3. Project Joining Difficulty: How challenging is it to get assigned to a project at Capgemini? Is the difficulty level comparable to the initial hiring interview, or is it more demanding?

4. Job Security: Considering that new hires are placed on probation, how secure is the job at Capgemini during this period?

Thanks in advance
