As user I want to see a list of the offers available on the event. For each job offer I want to see the following data:

• The title of the offer linking to the detailed offer..
• The company logo linked to their web page.
• A trimmed version of the offer or its summary.
• A link "Read more" linking to the detailed job offer.

Ready to be reviewed by the front-end team.
