Interview Process is very smooth Shivangi HR is Very Co-operative and friendly nature Great HR person but Interviewer is not good because lack o f knowledge about technologies and data structure Why I am saying this thing about interviewer name (Uttkarsh) definitely I will explain you 1. The formula for sum the interviewer was not known when I was conceptualizing the missing number. he told me your concept is right but your formula is wrong... Wah 2. Rote questions because he asked me Which collection have you worked on in your project? then I said ConcurrentHashMap and HashMap but jo questions phle se prepare kr ke aaye the wo puchne lage wah tb fir puchne ka ky mtlb which collection have you worked on?? 3. Array likhte kaise hai java me ye bhi confuse hona bahut sare example hai then I can say ******lack of knowledge about Java**** <<--- For Interviewer may be interviewer ke pass experience ni hoga or syd first time hoga interview lene ka experience 4. Easy concept in 3rd party Api Integration through Spring Boot :> RestTemplate Suggestion : first Improve knowledge then take interview Hope You are understating my point Thank for feedback !!!!!!
