This CV is too concise and leaves the recruiter with too many questions. If you do not supply the necessary information, there is a chance that the recruiters will assume the experiences have been negative. To avoid negative assumptions, it is advisable to briefly mention your previous tasks and accomplishments, even if you do this in your letter as well. Sometimes selections are based on CVs alone.
Do not forget about a logical and systematic when-what-where structure. Add some formatting and be consistent in the presentation of your information.
