Well, if you are looking to work locally I suggest you search job listings on @Bayt.com or @Akhtaboot The Career Network
if you want to work outside Amman Freelancer.com is a great website, as well as Upwork.com or elance.com but my favorite is Guru.com
Thats a hard one! Coz thats the weekend for most companies but you can work at restaurants and cafes or even at the mall if you find the right listing on @Bayt.com or @Akhtaboot The Career Network
Here is what I recommend to get more experience on your CV, maybe you can go to trainings in institutions like @SAE Institute or @Pioneers Academy then you can apply with confidence through @Akhtaboot The Career Network and @Bayt.com and there is a new site called tanqeeb.Com .. Good luck
@Bayt.com & linkedin.com are your best choices to find someone to help you designing an app. You can search people there by their experience and skills then you can contact them easily
There are lots of jobs for English speakers just depends what you want and your fluency. If you want teaching then look into schools or centers like @Nell Program. But if you want another field of work look through @Bayt.com or @Akhtaboot The Career Network for job postings
There are a lot of available jobs, it's depends on which field or sector she's interested in.. she can creat an account on @Akhtaboot The Career Network and @Bayt.com and apply for jobs that don't require a degree in their requirements
Check out @Khireej.com , @Bayt.com and also @Akhtaboot The Career Network employers announce for vacancies there for different educational degrees, you can search for a job based on your degree as well
It depends on what that person is looking for but @Akhtaboot The Career Network and @Bayt.com sometimes post internships for teenagers. But also check out volunteer programs @Injaz or directly call the companies you are interested in and they will tell you if anything is up for the summer :)
