Preguntas de entrevista para el cargo de Frontend Developer en abra

the home assignment is just react and redux , nothing to ellaborate. the interview with team lead- the worst interview I've ever had - an arrogant team leader who asks questions and doesn't let you answer, guesses what you want to answer and disdainful and arrogant behavior Overall . Even if you know the answer he will say - ok I will accept, did not ask at all about the assignment and said he did not look at it but someone else did. question i got ask - useDebounce- how not to waste api calls, what is seo, given an array with numbers, how do you find which number appears more than once (it is aimed at using a dictionary and any other answer is not accepted).
