what is career after Phd from HHL?
List of previous employment ?

Obviously a PhD prepares students for careers to teach and research in higher education.

HHL PHD is part time , is it good for good placement?

Into academia, yes if, as with any other PhD looking for an academic role, you are able to publish a paper in a good journal before you complete.

I should write a little longer about this. In Germany the PhD is uniquely credible as an award for senior managers, and that is why the country has a similarly unique share of its PhDs which are awarded to part-time or external candidates, many of whom have short registration periods and little of the doctoral training found at global universities. HHL's US accreditation and international orientation mean that its PhD is a better preparation for the international academic job market: indeed, many US business schools will refuse to hire from excellent universities that lack the AACSB accreditation which HHL and other top schools hold.

Academic work is more demanding than it was. As a result, business schools want to hire faculty who can continue to research independently and get published in respected peer-reviewed journals, and also teach at or above the level expected. Sadly many German PhD graduates have not had teaching experience, and their research work has been directed closely by their departmental chair. As a result they are not well prepared to research or teach independently. That is, as far as I can judge from meeting folk from/at HHL, not an issue at HHL. So, I think there are good openings for teaching roles after the PhD at HHL.

That said, while HHL is a better place to teach than a German state university it is still a school deeply marked by the norms of German academia. Life is hard for junior academic staff in Germany, with low salaries and large workloads, especially huge teaching requirements. If you wanted to work outside Germany, then you'd realy have to think carefully about how to get into the leading edge of a current global conversation in academia, rather than a duplication study or a topic that is totally orthagonal to the research questions in the top journals.

thanks Duncan.

Can you guide about HHL interested research proposals and what are good topics for Phd.
I want to work for good career after Phd either will find job in Germany or outside Germany.

Yes, that can quite a complex process but that is certainly something I can help with. Take a look at my profile page for details of my summer sale.

I had a follow-up conversation about this with a person familiar with the PhD options at HHL. They recommend, very strongly, that you don't take the part-time PhD if you want to work in German academia. The part-time option is so often used by people looking to stay in industry that the part-timers don't get the necessary access to academic networks and hierarchies. If you want to teach in Germany, take the full-time route: get hired as a research assistant and research the topics favoured by the professors.
