I completed my application process at eleventh hour making a sloppy mistake, which I hope gets neglected. However, after completing the process I stumbled across Hertie's annual report stating to admit around 335 and 376 candidates in MPP program and around 202 and 205 candidates in MIA Program for year 2019 and 2020 respectively. And in further bifurcation 50% candidates in MPP and around 25% candidates In MIA are from countries outside Europe. And in one of the sessions I attended, they claimed to receive around 800 applications for both the programs. So, by preliminary calculations- acceptance rates is quite high. What I have observed during this thirty minutes research is that Hertie prefers to add people with relevant work experience in their respective fields. Although there are many students with fresh undergraduate degrees as per one of the students I came in contact with during the process.
For Scholarship- especially IGYLF, I was given a suggestion to keep my SOP and Scholarship essay in consonance and single coherent narrative, since a panel which shortlist the candidate for interview includes professor from Hertie who reviewed your CV and SOP already. Having 2 spots for this scholarship opened to all the nationalities, but for the sake of argument if we take Germans and Indians as major contenders, this scholarship becomes a real competition because the major seats belong to Germans and high density of experienced Indian essays. It doesn't mean chances of any applicant is less but the scholarship is competitive in nature. It is followed by Skype interview lasting for 30 mins and discussing various aspects of your CV, SOP and Essay letter, basically if you are expecting a call, try to be through with your submissions and sketch out a plan on how you can implant your stated ideas, if given a chance.
However, based on financial needs, I am given to understand that 25% grants are usually dispersed for students genuinely needing one.
Ironically, I came across Hertie's opening for master around 26th (which I assume is the time you guys finished submitting) and completed my application process couple of hours before only. Surfing through their website to sooth my anxiety, I found these informations and now I regret of not doing the same before.
About the profiles regarding admission in MPP and MIA you find that both are dominated by social science (54 and 66% respectively), Business and Economics (21% and 17%), Humanities (10% and 11%), Law (9% and 3%) and Science and Technology (6% and 3%). Ironically, law as a discipline doesn't look strong in either programs.
Finally coming to duration of recieving response, they mentioned in open session it to be 4 weeks and this is corroborated by chats on this websites by people applying in the months of November-December.
And people applying after today- All the best!
