Easy, quick, simple, they asked why do you want to work here, tell me about your interests and what makes you think you are a good fit for this position.
Very straight forward. Asked about previous experience, strengths and weaknesses. Explained the job requirements and tasks. Asked all the regular questions. It was very smooth, and it didn't feel very timid.
Very easy, they just ask u ur availabilty not too hard and not something you would need to prepare for or anything. I also wore jeans too and they did not mind
