Best interview tips!

[interviewhelp25]

It's looking like I'm going to lose my job which I've been at for 9 years
I have an interview coming up and I get really really nervous with them
I've done a phone interview with them, and they emailed 2hrs later to ask me for a face to face, they've also said they will do an evening if needed (guessing that's good)

Any tips?

You could spend some time beforehand thinking about times when you did a good job. Was there ever a crisis that you helped them get out of? The bosses tend to forget this kind of thing, so take any opportunity to remind them of the positive role you played. Make a list the night before and write it down. Good luck!

Depending on the role, they may ask you for examples when-type questions (can you give me an example of a time you had to implement an unpopular opinion/when you completed a difficult task etc).

Try to think in advance of what might be asked, typical to the role/job, as it will help you recall them much easier on the day. If you feel you might be asked some things that you haven't directly experienced yourself, you can always think ahead of some examples you can refer to where you've seen someone else: "I haven't directly lead a team, but I was very impressed with a previous manager who got ideas from the team and included all colleagues in feedback...." It will show them how you might behave in that situation.

My tip is don't think of it as a performance but try to get into collaborative mode. Treat it as if you're helping your boss or colleagues solve a problem.

I have had more than one interview where they asked what my understanding of the job was, helped to have a good grasp of the job description.
I found it really useful to plan answering questions using the STAR model... situation, task, action, result. Eg we needed dinner, I offered to cook, took note of allergies/preferences of diners, chose menu, checked cupboards, bought ingredients, cooked, result, we enjoyed dinner. If appropriate then add reflect at the end...would have been better with roast potatoes rather than mash.
Thinking about answering in that format lets you emphasise what you did, stopped me rambling, and if I was planning how to answer expected questions it gave me a chance to think about different examples for different scenarios.
I like to try and ask a question about something on their website to show I had done some research.
Good luck.

One more tip is I burn my nervous energy by going up and down the emergency stairs or getting on the treadmill at home before the online interview. I also put my hands under running warm water for a while because my hands are icy and clammy when I'm nervous. It helps ground me a bit.
