Our Call Centre
ILRES conducts over 20,000 telephone interviews each year via its own call centre in the Grand Duchy of Luxembourg
Trained, multilingual interviewers
We work around the clock with a team of regular investigators, who can be reinforced if necessary. All interviewers are trained and supervised for each survey by a manager who ensures the quality of their work.

As part of our rigorous selection process, all our telephone interviewers take a thorough reading test in the country’s three official languages.
In addition, we carefully assess their ability to express themselves clearly and effectively in each of these languages, to guarantee the quality and accuracy of our surveys.
Enhanced interview tools
Our CATI (Computer Assisted Telephone Interviewing) system makes it possible to dynamically distribute calls to different interviewers as well as a wide range of functions such as setting appointments for call-backs, monitoring survey progress, managing and checking sample composition, and carrying out quality checks.

ILRES uses a predictive dialler, which dials the telephone numbers contained in the database created for the survey. ILRES has its own database of generated landline and mobile telephone numbers called random digit dialing (RDD) which it can use to create probability samples.
Based on requirements, it can use client-supplied contact databases. The use of telephone numbers in the survey database is optimised by easy contact management and the appointment option.
Interviewers use a programmed survey system that gives them complete control over how the survey is conducted and ensures quality data collection. Thanks to its technical capabilities, ILRES is able to offer people contacted by telephone the option of taking part online. This alternative solution is particularly popular for B2B surveys.
