Potential Post-Doc supervisor visit: should I give a talk or just have a meeting? I am a PhD candidate in computer engineering. I saw an announcement for a post-doctoral position on the internet. 

I wrote to the professor having that open position asking him if I could come to visit him and his lab, and talk about the position.
He replied yes. We agreed on the date and I asked him if he wanted me to prepare a talk with slides to give during the visit.

He answered:


  You are welcome to give a talk or we may just have a meeting. It's fully up to you.  


So, what should I do?
Talk or just a visit?

A meeting would be more relaxing and confortable, and provide no stress and no extra work.The talk would need time to work on it, and would be more stressful, but may explain better my previous research projects..

What do you suggest to me?
Unless told you shouldn't, you should always opt to give a talk under such circumstances. It makes discussions with your potential future advisor and group members much more meaningful, because your interviewers now have a much better sense of what you do. 

Moreover, a solid presentation of technically sound research shows that you have achieved one of the most important skills needed for a researcher: the ability to effectively communicate your work! As a postdoc, your advisor is going to expect you to have most of the research skills needed to complete your work with minimal supervision. Giving a good presentation will clearly demonstrate most of your credentials in a way that a face-to-face talk will not.

Finally, giving a talk to a (mostly) friendly audience is always good practice for your future career. (People get better at giving presentations by giving presentations!)
