Perguntas de entrevista de vagas de Full Stack Web Developer da empresa Roche

recruiter reached out on LinkedIn. followed by recruiter call of 40 mins and then tech screen for 45 mins. They insisted on taking tech screen as soon as possible and set it up on random time which was not given by me. However I made arrangement on that day and took interview. The interviwer had joine company 5 months back and was very rude. He asked very very basic questions and in 30 mins he said this were the all question i had prepared for me. he asked me 1. how would you print hello world in react. 2. how would you have input box and on each character enter show alert in react. 3. button inside button and when inside button clicked it takes action as well as outer button function gets executed. how would you avoid this behavior. thats it. there was no explanation given on rejection. Questions answer correctly with proper explanation. WORST EXPERIENCE.
