Hi, I 've received an offer for a Phd in Mechanical Enginnering and the supervisor would like to meet me.
What do I have to expect from this meeting? What does he want from me? Do I have to consider this like an interview for a job?

I start my PhD in Electrical Engineering this October. I have met with both my two academic supervisors, and my industrial supervisor - and I treated all like a formal job interview. That means dress fairly smart!

All three meetings were fairly rigorous. During the meetings, we discussed my ideas for the project at length. Then they probed into how serious I was about research, and finally my two academic supervisors set me on-the-spot mathematical problems to solve in front of them.

Preparation is key, the more you do, the better equipped you are for the interview!

Good luck!

There's lots of opinions on interviews on this forum - search for interview for more information than you could possibly need.

Most PhD 'interviews' are quite informal, but do require you to come across as interested and capable of completing the project. In your case, you already have a PhD offer and the supervisor has asked to meet you. This should mean that it is definitely not an interview, he probably wants to give you some initial reading material and discuss start dates and what your working relationship will be. PhD students tend to start at the same time as undergraduates and this can mean that supervisors are very busy in the first few weeks. By seeing you before you start he is making sure you'll be able to get started even if he's busy.

Yeah I had a meeting like this with my supervisors. They just wanted to make sure I knew what I was letting myself in for. So it was very informal. In fact it really wasn't like an interview at all apart from a few standard questions.

I have completed MBA & BBA from Dhaka University, Bangladesh. I want to be a PhD Student with Scholarship. Now I am working as a lecturer in Manarat International University, Dhaka, Bangladesh.
