GSK Research Scientist interview questions

Initial phone call with HR followed by technical call with hiring manager then on-site interview. The on-site interview consisted of 45-minute panels from 8:30am-4:30pm with a one hour presentation and one hour “lunch break” during which I was questioned the whole time. The entire day was like an interrogation and even my presentation was interrupted every 10 minutes with questions. After all this I was sent a rejection email almost one month later saying they decided not to fill the position.
