Nagarro Senior Frontend Developer interview questions

First there will be a test on Mettl, followed by 3 rounds of technical interview, if you pass that test. Test on Mettl: It'll have 3 sections - Aptitute, Basics of Angular and Javascript, 2 codes. Test duration is 90 minutes. I don't see the logic of asking silly aptitude questions like average speed, upstream downstream to a 7 year experienced developer. However, the aptitude and syntax sections are pretty easy. Coming to the coding part, Mettl doesn't even support Javascript 2015 version changes and it was not mentioned anywhere. It took me 15-20 mins to figure it out and make changes in my code. Debugging option was also not there on Mettl, which made my life very difficult. I cleared the test and was called for 1st round of interview. I was asked basics of Javascript and Angular, which I did good. I got another call that I got selected to the 2nd round of interview. I am a 7.5 year experienced guy and I got interviewed by a 6 year experienced person. I answered most of her questions, but only they should know why I didn't get selected
