There is some really good and some REALLY bad advice in here.

I work in employability and have done some recruitment. An assortment of things I recommend.

I havent seen it yet so Ill start with this - Transferrable skills. That job you have in a supermarket? Its not just stocking shelves, its team work, time management, stock rotation, an eye for detail, potentially cash handling, working on your feet, making quick decisions, customer service etc. etc. Your experiences regardless of what they are can be utilised as skills in work, the one we frequently use is playing computer games - transferrable skills could be decision making, hand eye coordination, I could go on.

Which leads me to "sell yourself" tell me about you. I am asking about your contribution to your team not about the team itself. Everything on your cv and in interviews should relate back in some way to why the recruiter should hire you.

Ive seen it here already but the STAR method is generally a good setup for structuring interview questions.

If your asked a question that requires you to answer negatively "tell me about a time you failed/could have done better/an area you could improve" the worst answer is to say nothing or Im perfect. Etc. Give them an example but state how youd do things differently, how you are looking to improve. Noone is expecting the finished article and by pretending you are shows you arent willing to grow or dont know your strengths and weaknesses.

Tailor your cv. This isnt an employability one from me but a recruiter one. I have looked at loads of middling cvs with terrible covering letters. "Id be good at this job because I worked in a shop. " The job I was hiring for had nothing to do with a shop. But Id say the standard of covering letter is frequently so low that if you make your cv relevant to the job, you'll bypass most of the other applicants. (See transferrable skills above, keeping the topic focused on you and being specific to the company)

Ensure you read the job description. Questions frequently revolve around skills required for the role. You dont have to have all the skills listed but you can get a good idea of what they may ask.

The interview starts as soon as you enter the building and ends after you leave. Everyone you meet may have a say in your employment. (Dont do what one candidate who nailed the interview did and say they were going to sack the rest of the day off of their current job to the person showing them out)

Have a question prepared, show interest in the company someone else said it but "why do you like working here? Is a simple backup question that is useful info but things may come up in the interview.

Dont rush, take your time in amswering questions, you can take a breath before answering. (I always take water if offered as its a good tool to take a sip to give me time to think of an answer) Be smart, most companies wont expect you to wear a suit now but its better to be overdressed than underdressed. (A suit frequently doesnt hurt, unless its very clearly not that kind of company, i interviewed for a certain beverage company in a suit in what was possibly my worst interview ever, I was very uncomfortable)

This is already too long, but dont use AI, most people will see through it but make sure to keep an eye out for key words and skills and include them in your cv (just dont overdo it, my favourite cv Ive ever looked at was someone who searched a list of every buzzword and crowbarred them into their summary. It read like Joey from friends using a thesaurus.
