Dear Sir/Madam,

I was interested to see an internship proposal at the Career section for “Machine learning of hotel customer behaviour”, and would like to learn more about this opportunity.

I recently graduated with honors from National Technical University of Ukraine “Kyiv Polytechnic Institute”. My subject area covered neural networks, automation and general modelling.
As an engineering student I worked on a program development, analysis of project concepts, building models or algorithms and programming according to them in team and alone.

Having read key information about Amadeus on the website I feel that some of my skills and knowledge would be at use in your company.

Thank you for your time and consideration. I hope to have the opportunity to discuss the opening with you in person.

Sincerely,
Me)
