Remember that you are also interviewing them. They won’t expect you to know all the answers, but will want someone that they can work with. If you can, answer questions with the STAR method (situation, task, approach, result), but don’t waffle. You can use one piece of experience in a variety of ways: teamwork, research, urgent deadline etc.

It’s ok to say that you are nervous, they should try to put you at ease.

You may be asked ‘trick questions’, these are not usually to to you up but to see how you work an unknown problem. There is no right answer. Not knowing stuff is ok. Not being able to think up a plan is less so.

Remember whatever the outcome, this is really useful experience. See if you can get a site tour, ask about the tech used… You can then add this to your knowledge for later. In my experience, industry is frequently several years ahead of academia so you get a good chance to understand the real world.

Yes prime minister is the most accurate documentary about British politics of all time.

many technical jobs are vocational in nature as it’s impossible to turn it off after work. As long as it’s not affecting your personal life & work life balance (and not affecting your friends and relations) then you are very lucky. Most people don’t enjoy their work so you’re in a good place. Importantly though, don’t feel obligated to do work problems on your own time and don’t let management expect it. Only do it if you want to.

I like the saying “give a man a job he loves and he’ll never work again”. it’s been true for much of my working life.
