I just want to add that even after you have a job and you love it, it's still a good practice to keep sending out resumes for job postings. That way you can keep yourself updated and practice what works and what doesn't. You can just say that you already got another offer if they eventually want you for interview. I know it's a waste of time for those employers out there, but there's only 1 way to learn and it's by practice and it's better to practice while it's not your life hanging on it.

Perhaps this is only in LATAM or Mexico, but here what they wanna know right away is what you've done and for which companies, so in this regard I would recommend you to put the very best of your work and if you've worked with big companies put that work in front of everything.

After they know what you can do and for which companies, they wanna know the companies you've worked with and position on those, why you changed and why you're willing to change jobs or why you were unemployed.

Then they wanna know more info about your knowledge like courses, schools, college, etc. Also about you, your personality, pros and cons of having you and abilities as a human and a worker.

And in a less important way but important at the end they wanna know your hobbies, your goals and things like that so they can 'figure out' if you are needy enough, you will be loyal enough or if they are going to have someone that works for them just a mont, a couple of months or years and years.

Also now in LATAM or Mexico companies wanna know if you can work in a stressful environment, short deadlines, extra hours without pay (I added the without pay 'cause is very rare to work in a company that pays extra hours), work in a kind of hostile environment, and some other kind of questions asked nicely but with stressful stuff and not ideal conditions.

People want to know, quickly:

• What you can do - broadly. Are you a focused specialist or a generalist? Do you learn every latest thing or deep dive on core tech?
• Where have you worked and for how long. What kind of companies, what roles, duration of roles... what's your work story basically.
• What training do you have
• Do you do extra professional stuff like speak, write, etc

Try to keep it short and easy to digest. People are busy. They're not reading your CV, they're triaging it. On the first pass they're going to read headings and dot points, they're trying to form a quick picture to see if they should read in more detail. When they read in more detail they're deciding if they want to interview you. But they will not read your life story at the first glance.

Experience , Key-Words ,Projects , and most important thing is "Expected CTC". Except from these stuff all are garbage on your resume.Because mostly time recruiters (HR) not technical.

There's a tool called Novoresume and it's pretty cool. Another one for developers is DoSelect I came across which builds your developer resume. You can integrate your GitHub and Stack Overflow accounts also. It's really cool.

Critical: Spell & grammar check before you publish. Then get someone to review it for you.

Content (in the following order)

1. Contact details + (github repos etc - optional but recommended)
2. Personal statement + (expected salary - optional)
   This is just why you want the job and how you feel you can help them too.
3. Skills (relevant to the job)
   Preferably in bullet-points or something similar to this: Blue dots on skill Personally I hate this method of portraying skills as it is completely arbitrary. However, it does seem to catch the attention of many employers due to it's "modern style". This will be used as an example throughout this answer.
4. Employment history
   The format in Modern CV. is a good one to follow, always include dates on employment - do the same for education.
5. Education (briefly)
6. Outside interests and others (if you like & optional)
   A simple 1 or 2 line description is fine here.
7. Certificates/awards
   Again, more like bullet-points.
8. References

Styling

1. ALWAYS IN 3RD PERSON NEVER FIRST.
2. It has to be viewable at a glance.
   People don't have the time, and at the beginning of the process don't really care about candidates until face to face meetings. Therefore the CV MUST have key skills and employment easily readable.
3. Type of CV: As a designer, and sometimes a developer, choosing a website, EXAMPLE, as your CV is usually an excellent idea. This would obviously mean that most of the content mentioned above still applies + social media etc. Obviously references wouldn't go on there.

Otherwise I would go with the Modern CV as a styling reference and work from there.

Finally

For me a CV should be no more than 2 pages, although I know many would potentially disagree with this. My reason for this is 2 pages are enough to fit the critical information on, and yet also not too much that an employer would get bored/care less with the amount of information received. As an old friend once said

Information density.

I did actually consider making a Udemy course on how to write a CV because the amount of crap out there is just depressing (see critical point at the top).

The resume I currently have got me call to interview most of time I applied somewhere (recently I have not applied to any company, but you will get the idea). It consists on few basic things, and one is particular important: tell as much about yourself in little text as possible. So here's what's on my resume for example(I will send it to you if you are interested, feel free to copy it) :)

On a left side, on some 1/3 of a page:

Top left corner, I wrote something like this: your name first . It will be useful to write this. :)

Beneath: Hello, I am software developer with more than 5 year of experience in languages and technologies like(list the technologies you are most experienced with) . With this you are telling the 3 important things for HR manager to quickly view who you are: software developer, 5 year experience and technologies you work with. Often they don't have time to read massive text, so this will be quick way to immediately draw their interest to keep reading.

Beneath: I am also familiar with(tell some more things you have worked, in one sentence). This will tell them more about things you have learned over time, and if you applying for some specific position for which they are asking some technologies you worked with, named it there. I am currently learning (name language or technologies you are currently learning). It will tell them that you are always willing to learn new things. :)

Beneath, bottom of the page: put your contact details(e-mail, phone, linkedin, github etc.)

On a right side, on some of 2/3 of a page: Put some basic info, like: I am born on some year, live here and here, speak language that and that. - it will tell some basic info, as also languages you speak

Beneath: put your education. It will tell them what education you have.

Beneath: Put your current work position in company(if you have one) and some basic things you work on daily level. If you have some interesting projects you worked on(web applications or etc. that are public accessible) put links to them.

Beneath: Put your last work position before current(if you had one) and same things as with current company.

Beneath: Put your off-work activities, like if you are in some organization, you like something etc.

And that's that. It will take only one page, and for me that's enough. These are not rules, these are something I have came up with a little research over the years, but it served me well. :)
