As a part-time lecturer, this is the first time that I have been assigned to drive a bachelor's thesis. I try to convey to them my interest in their project. And, I also recommend them to be in contact with me. A student asked me for my personal phone number, and I gave it back. We have exchanged a few WhatsApp messages, always, all of them work-related. Nevertheless, I have serious doubts about if it is professional enough to use this means of communication. And if I should avoid this in the future.
