1) Know yourself and what you are looking for: Easy to say but more difficult to do.
It took me 5 years to understand what I like and do not like in a job/industry, and 3 different positions and companies.
It is likely that what you liked during the masters might also be what you like in your job.
Try to focus on positions/jobs that reflect your attitudes and liking.
I am Mattia, and I commenced study at WMG on the MSc in Supply Chain and Logistics Management (SCLM) after more than 5 years of work experience in the financial and banking industry in London and in Italy (my own country).
I decided to change my career because I did not fully enjoy what I was doing in the banking sector, and I thought (before starting the masters), and I now strongly believe that Supply Chain Management and working for a manufacturing company is what I would like to do in my future career.
This, on top of the Masters work, proved to be very challenging, but I believe it was worth the effort.
I have some colleagues that also started early and they secured jobs months before the end of the Masters.
Nevertheless, I decided to attend some of the 'Student Careers & Skills' services seminars, in particular how to build a CV and a Cover Letter, and some one-to-one sessions to assess the quality of my CV.
This was very useful and allowed me to modify my CV to be in line with the UK market expectations.
