Jobs

Right away, take one of the basic Torn jobs.  Grocer is my preferred choice, but army or casino will also work well.  These are the basic Torn jobs.  Those jobs will let your work stats start rising, which will make it easier to get a job with a player owned company later.

At some point, you will probably want to look for a job in a player-owned company.  Sweet shop is usually the best place for a new player.  Those have low stat requirements.  And in a sweet shop, you want the company to have at least a 7* rating.  Less than 7 stars doesn't allow you to turn in job points for energy cans, which is the primary benefit of sweet shops.  (Those energy cans can be sold for $1M to $3M each.)  Plus, your # of job points gained each day is based on the # of stars, so more is better.

Companies also get a limited number of trains to give out each day based on # of stars.  A 3* company gets 3 trains, a 10* company gets 10 trains, etc.  So more stars means you'll get trained more often.

I would avoid accepting any job from a company with a low # of stars.  At least 7* for sweet shop.

Be willing to work for free, especially in your first job.  Some companies pay, some don't, and none pay very much unless you have very high stats.  (My company is a 10* fitness center, requires high stats to do the jobs, and still doesn't pay much.  But the benefits of working there are awesome. ) Jobs are mostly about the perks of that job, not the money.  TV and Oil companies do pay a lot, but have very, very high stat requirements.

When I go looking for a job, I decide what kind of company I want to work for first, then I list all of those companies.  Clicking on Newspaper, Job Listing, Sweet Shop, for instance.  They will be listed with the 10* companies first, the others later.  Look at the company names for those that include "hiring" in the name.

Once you find some that say Hiring, don't just apply.  Message the directors first.  You can only have one application in at a time, so you're better off if you msg directors from several companies, and only apply after they've told you that they'll hire you.  

When you msg them, tell them your work stats. (Manual, Intelligence, Endurance.) And assuming you are active daily, tell them that.  Company directors are going to want someone who logs in at least once a day, and they are going to want to know what your stats are, so make sure that info is all in the msg you send. Most companies will train their employees in rotation, but you might want to ask about their training policy in your msg just to be sure.

When you are brand new, you have essentially no work stats.  Working the basic Torn jobs will help bring those stats up.  And it shouldn't take long before you can find a company job.  Those usually have better perks and usually they will train you.

Over time, you'll want to do different jobs.  At some point, you will probably want to do the basic Torn jobs for education, medical, and law.  Those all give permanent perks when you reach the top level.  You keep those perks (lower education time, ability to revive, increased crime success rate) after you leave the jobs.  And company jobs have lots of different perks, so you'll probably want to do different ones at different times as your goals change.

I hope this helps.  Good luck.
