Nagarro Devops Engineer interview questions

Total 4 rounds of interview 1st round apptitude, 2nd and 3 rd round technical interview followed by 4th round Hr interview. Nagarro interview is difficult. Interview process is very long.

very difficult technical round compared to hcl, Capgemini, tcs, TechM, they asked difficult technical interview question from me but all other things are okay, they take aptitude test also which should not be for experience guys
