In my field (Computer Vision), the largest international conference (CVPR) has the following format: two simultaneous oral sessions (with talks awarded to ~10% of accepted papers), followed by a single poster sessions (awarded to ~90% of accepted papers). I have recently had an oral presentation of my work at this conference, and I am now writing a cover letter for a job which will be reviewed by a non-specialist, who will not necessarily understand the prestige of such a talk.
So, rather than writing "I was awarded an oral presentation of my work", I'm wondering how fair it would be to say "I was awarded an oral / plenary presentation of my work", to indicate that the oral sessions are to half of the entire conference delegates. If I just wrote the first option, then it may be assumed that the oral sessions is just with a small group and among many simultaneous oral sessions, as is typical at many conferences.
So would it be correct to say "oral / plenary", or does this imply something even more prestigious (e.g. a keynote)?
