in germany, they have specific title for every field instead of general 'phd'.
hence, a doctor of medicine is given Dr. med, a doctor of economy Dr. oec. and a doctor of music Dr. mus..
Heck, they even gave specific title for their undergraduates (prior to bologna process).
Dipl.-Ing. for engineering graduate, Dipl.-Kaufm. for business graduate (Dipl. titles for applied sciences), Mag. art. for arts graduate, Mag. iur. for law graduate (Mag. titles for social sciences)
and germans are most-obsessed with academic titles.

i am planning to pursue doctorate (in german is called promotion) after working for 2 years.
so, probably late this year or early next year.
i am lucky because i graduated with an old german undergraduate degree which is equivalent to master.
after 5 yrs of study.
half of my classmates went straight to do doctorate after undergraduate.

in germany and probably in many other developed countries, phd can be pursued in the industry.
i.e. you work at a certain company as phd student/candidate rather than at school.
(heck, i even completed my final year and undergraduate thesis while working at a company)
usually companies advertised this position in their website or job bourse, specifically looking for a phd candidate.
the candidate, when successfully selected, will work at the company like normal workers.
he/she will be given one projects that related to his/her phd. (this usually for applied sciences candidates)
apart of that, he/she will be given other tasks demanded by the company, as well.
he/she is treated as part of the company, received salary and benefits.
the downside is, all his research works will now belong to the company.
but he/she is still allowed to published the work under his/her name.

after completing the doctorate he/she can stay at the company, or pursue employment at other company.
not many end up as lecturer (like in malaysia).
you need to have many years of industrial experience before you can teach.
at least in engineering.
the universities usually will looked up among those in managerial position and ask them to teach.
most will take the job not because they need the money. (the pay is not that great from what i heard)
they took it up because they considered it an honour to teach.
they usually give lecture once a week on one specific topics.

those who want to teach straight away, must 1st enrolled in professorship program.
they will become teaching assistant (tutor) for at least 2 years (depending on the uni) before taking an exam for full professorship.
if passed, they can get another title habil. attached after the doctor before the specific field (not for engineering).
the full name is Habilitation, which is a license to teach. (mostly in classical universities).
applied sciences universities have an easier route.

most importantly, majority of successful doctorate candidates pursue employment in the industry.
they usually have the job title technologist or researcher or r&d/principal engineer.
and they get big bucks, usually 6 digit salary.
