Telephone interview then face to face interview. The overall interview process in GSK takes time as they need to interview multiple people and multiple times. So be patient. Once the offer is made, the background checks process (by Security Watchdog) will start which is very comprehenive. They will perform background checks from min 5 years and max 10 years depending upon the role you applied. GSK gives utmost importance to integrity and ethical values. Never, ever lie about your work experience, roles and salaries. Once you join GSK you will really feel the proud of being in GSK.
