Initially an HR told me it will be 2 round of technical and end up with 4 round of technical. the best part is, initially they were looking on REACT and Redux developers at finally i.e., at the end of 4th round they come to know they are looking for "REACT NATIVE"... ha ha ha bad to know at the last round of interview @ 4th round.
I request you to just define the scope of technologies which your are looking at, instead of wasting time with a candidate.
1st round - 20 Mins
2nd round - 30 Mins
3rd round - 1:30 Mins
4th round - 1 hr
Time is too costly for everyone.Thanks for understanding.
Want to tell you at last about the HR : the guy who has taken an HR round really am fail to understand what kind questions is he asking. Request you to prepare well before asking any question (it minds a lot)
