I work in technical consulting on projects that include 1, maximum 2 people. At the end of each project, my firm sends the customer a feedback form with 5 simple questions - it is a KPI for the whole department and for single employees.
The result is a score between 1 and 10 plus a short positive comment, which are both usually very dependent on the lead consultant, due to the team size and type of work.
Is this feedback something that could be included in a resume? How?
The goal is to prove that clients are happy with my work, without sounding like a potential employer is reading an Amazon product review or a humorous dating profile.
I am currently not looking for a job, but I could not find similar questions on the site and could be useful for others.
Edit based on comments
Over one year I carry out and manage 10-15 projects; I would not include the single comments in my resume, but a one-liner in the description of this role (e.g. "90%+ customer appreciation over 20+ projects") just like I would write something along the lines of "Project manager for a total of $500k with a 30% margin"
