I hope you’re all doing well! I’m currently in the process of revamping my CV and wanted to tap into this awesome community’s expertise.
I have a few questions:
Hi Ibby, its great to see your first post in the community. To answer to questions, there is usually a common theme when it comes to how to section your CV although it is not a hard standard. CV commonly start with Name and Contact details (email, phone, address) followed by a personal summary (brief intro to you - uni, course and what your are trying to achieve currently, an internship?). 
Next I would have to say Employment history and work experience since this will be the most relevant to employers who want to know your past. This section should be in chronological time order and you should try to have relevant experiences on there (could even be part time retail - working as a team). After that would usually be the education and qualifications section, again chronological order with your most recent qualification at the top (BSC, MSC, …), you can also put other qualifications like NCS or Duke of Edinburgh in this section. Lastly I would highlight any volunteering I have done and a hobbies/ interests sections to give the employer a more whole picture of you.
A CV is like your passport of your life (it highlights where and what kind of work and studying you have completed), therefore it should be a formal piece of document that is as concise as possible, you should also focus on making it as readable as possible (bullet points, sectioning and maybe even a little bit of colour, stick to more formal colours like navy blue). Remember the employer on average looks at your CV for about 6 to 8 seconds so you need to make sure you catch their attention in a positive way. The Covering Letter is the place to boast about yourself a bit, it allows more freedom in terms of what you say and how you say it.
Do: edit every CV to match the job you are applying. Do: get a few people to proof read.
Don’t: leave application and CV writing/ updating to the last minute. Don’t: make it too flashy or informal.
I hope this helps. 
Hi @Ibby , great post!
@Yogi99 makes some great points. Also to add that recruiters are increasingly making use of AI to screen CVs, and therefore constructing a CV involves ensuring that you include key words and phrases that the algorithm can pick up and assign a positive value to.
This is an area that’s rapidly evolving. I’ve just done a Google search for
optimising your cv for AI
filtering results to show only content newer than 1 month.
Lots of interesting stuff there, and definitely worth 15/30 mins of reading.
