1st a telephonic interview (HR). 2nd interview conducted by hiring manager(On Zoom, lasted for 42 minutes). 3rd interview by VP Operations(On Zoom, lasted for 30 minutes). 4th interview by a senior software developer( on Zoom, lasted for 40 minutes). 5th interview by another software developer (on Zoom, lasted for 1 hour and 15 minutes). 6th interview by an IT support Engineer (at office, lasted for 45 minutes). 7th interview by third party "background check recruitment company", lasted for 1 and a half hour on zoom. Prior to this interview I had to do some personality, numerical etc tests, took me 1 and half hour. Then they contacted 3 of my references and got a satisfactory answer which resulted in another interview on zoom i.e. 8th interview (i.e. 2nd with hiring manager). He told me about how the teams are arranged and what is their approach/methodology towards work. Then after two days, I got a phone call and I was told that they are focusing more on the position based in UK and not hiring from Oslo.
