What is your greatest weakness?" with the answer, gleaned from articles like this one, "Well, I tend to work too hard and I need to put more effort into other aspects of my life."
The article says that "I tend to work too hard" is the bad answer. Their advice is to use something like "I'm bad at public speaking". However, I wouldn't use this answer for any job interview where you are expected to present your findings at a meeting (pretty much any science job). Like I said, not all of their advice applies to science jobs. I would find something else to say. In my case, the last time I interviewed I mentioned my lack of mouse experience as my weakness, which I believe is an honest assessment of what I am lacking. But this was for an internship position so the expectation was that I am coming there to learn.
But the link has some good answers. For example, for 5. Where do you see yourself in five years? it says:
“In five years I’d like to have an even better understanding of this industry. Also, I really love working with people. Ultimately, I’d like to be in some type of managerial role at this company, where I can use my people skills and industry knowledge to benefit the people working for me, and the company as a whole."
I could be wrong but I think it's fine to use this answer, as long as you tailor it to your own personal experience and the job in question (for example, if you are interviewing for a technician job, don't say I'd like be a manager in 5 years, but say something like " in 5 years I'd like to be in a senior technician position where I can use my scientific and technical expertise to benefit my team and the company as a whole"). It's hard to prepare for a job interview, I think sometimes it helps to have a template to work off of.
