Hello
I currently work in research, in a small but busy research institute in the U.K. I have been fortunate to work on many projects in my field of interest and have a good publication record as a result of this job. I am educated to Masters level and am now considering pursuing a PhD. My relationship with my Masters supervisor was poor, and we have not remained in contact in the 3 years since that degree so I am not confident he would provide a good reference (most likely just provide my overall grade), that's if he even responds to my request which he may not. I'm reluctant to ask my current boss as I would like to secure a position before giving notice, so am not keen on asking for a reference from him. I am applying for a position in Germany and was wondering if anyone could advise on the likelihood of an invitation to interview without references included in an application? Or, would a reference from a close colleague suffice, in addition to a character reference?
Any advise would be gratefully received!
