The #1 rule of answering this question is doing your research on what you should be paid by using sites like Payscale and Glassdoor. You’ll likely come up with a range, and we recommend stating the highest number in that range that applies, based on your experience, education, and skills. Then, make sure the hiring manager knows that you're flexible. You're communicating that you know your skills are valuable, but that you want the job and are willing to negotiate.
Tip: It can feel awkward to discuss your weaknesses in an environment where you’re expected to focus on your accomplishments. However, when answered correctly, sharing your weaknesses can show that you are self-aware and want to continuously get better at your job—traits that are extremely attractive to many employers. Remember to start with the weakness and then discuss the measures you’ve taken to improve. This way, you’re finishing your answer on a positive note.
Interviewers ask personal questions in an interview to “see if candidates will fit in with the culture [and] give them the opportunity to open up and display their personality, too,” says longtime hiring manager Mitch Fortner. “In other words, if someone asks about your hobbies outside of work, it’s totally OK to open up and share what really makes you tick. (Do keep it semi-professional, though: Saying you like to have a few beers at the local hot spot on Saturday night is fine. Telling them that Monday is usually a rough day for you because you’re always hungover is not.)”
Any candidate can read and regurgitate the company’s “About” page. So, when interviewers ask this, they aren't necessarily trying to gauge whether you understand the mission—they want to know whether you care about it. Start with one line that shows you understand the company's goals, using a couple key words and phrases from the website, but then go on to make it personal. Say, “I’m personally drawn to this mission because…” or “I really believe in this approach because…” and share a personal example or two.
