Good questions that I've come across:
How did you come to work for company x? Or What made you choose to work for this company? What's the best thing about working for this company? What one thing do you think everyone should know about this company? (All variations on a theme)
I see that company y lists x values on its website, what does that mean in practice on a day to day basis?
I see company x has links with Europe, what plans are in place to manage brexit? How has company x managed the covid situation/what impact has covid had on business/growth/turnover etc (or other topical question).
Anything that demonstrates research, knowledge and a bit of critical thinking is great, so pick something you know about the company, such as their 5 year sales target, and ask something insightful about how they're proposing to meet those targets for example.
As a pp says, don't ask something for which you could find the answer in the public domain. And don't just Google. Check linked in, other social media, industry publications too. I managed to build a rapport with someone who interviewed me by congratulating them on an industry recognition award their company had won, and asking what internally had led to the nomination.
A lot of companies expect the star approach to competencies. Star being situation, task, action, result. But it doesn't have to be so rigid. Think of it like this, you need to tell the interviewer what was going on, what needed to happen, what you did, and what impact that had. Sometimes the situation and task blur together. What is important is to get across is what you did and why, and how that solved the problem.
All of this is irrelevant though if you show up late, poorly organised or badly presented, either in person or on video. You still need to dress for a zoom interview, and take care that what is in the background creates a positive impression.
And always send an email thanking them for their time afterwards.
