1. about 1 hour for whole seminar, including 45 mins presentation and 15 mins Q&A.
2. I suppose the intended audience will be employees from different departments/groups in that company.
3 and 4. Yes I am getting a PhD and the job I am applying for is research oriented as well. But I read about interview experiences of some people working there and I didn't recall they gave research presentation when they were interviewing.

Is this a good sign or bad one if being requested for extra session in interview?

Look at it as an opportunity to showcase the work you have done. Not everyone gets that chance!

I wouldn't say it's inherently good or bad. It's an opportunity, like Anonymous above has already said. You could do a good job and impress people, or you could do a terrible job and have it hurt your chances.

If it's really true that they singled you out for this kind of thing, then that's probably a good sign. It means they find your research topic especially interesting or useful for the company.

Thank you eugene.yarovoi and Anonymous.

In addition, since I am new to the interview process, I am not sure if this is the question I should ask the company. I will be having several interview sessions during the onsite day, will it be ok if I ask them what will be the focus of each session? (eg. A is for programming, B is for problem solving, C is for behavior, etc). In addition, if I ask who will be the interviewers of each session so that I can check their background on, for example, Linkedin, will this be considered as bad thing? or they will consider this as proactive and show I have high motivation?

Thanks!!!!

You can ask about the focus of each session, but be prepared to not get an exact answer. The company may leave a lot of the questions up to the interviewers, and there is not always a clear plan. I wouldn't bother with such a question for that reason. You can rest assured you will be asked coding, technical questions, and resume / behavioral questions, so why do you even need to know when exactly you will be asked them?

I've never asked for the identities of interviewers. On one hand, it's proactive and strategically wise to learn who will be interviewing you; on the other hand, I feel it can be a little too much pandering to the interviewer, at least for a tech interview. Maybe others will disagree. In any case, you can do just fine in the interview process if you don't know who your interviewers will be.
