Work experience
The experience part includes your current job position and previous job records. We recommend filling your profile from the very recent experience and finally getting to the oldest one.
Pro tip: once you start filling in the company name and your job title, instead of typing the full title and then pressing enter, better select from the dropdown list. That is how LinkedIn links the work status with the existing company account on LinkedIn.
Speaking about experience descriptions, the whole idea of these descriptions is to summarize what you did in each role. Not copying and pasting full resume bullets but simply clarifying what that job entailed and using the opportunity to insert some keywords. Often, your title doesn't tell the whole story of what you do and the many different hats you may wear.
Some more tips on what to include:
Add some context of what you're doing at the company. You can present the company a bit more, by giving info on what it is.
In general, it's cool if you have a short bullet description of your work responsibilities, your KPIs, or work achievements.
You might also consider including a one-two sentence description of how you see your current or past role, such as:
Example: "As a restaurant manager, I ensured that the restaurant operated efficiently and profitably while maintaining its reputation and ethos. It required multiple professional and interpersonal skills to oversee the restaurant operations. In a sense, I believe that the restaurant manager is the leader of a team of professionals, and like any company, a manager must have leadership qualities."
As for the roles you found out are not for you - those can be used as your 'lessons learned' cases if you turn them around into something positive.
For instance: "I've worked as a car-washer only to discover that my organizational skills and passion for the order can be used in project management."
Include skills and subjects, and spell out the benefits you have to offer to an employer (fast learning, problem solver, entrepreneurial).
Try to focus less on what you know and more on what you can do.
Remember that companies hire for "culture" as well as competence. In other words, give some clues about the working culture you will fit into nicely. It will help companies understand if you're a good fit and hopefully land you a job in a working environment that you will like.
