Preguntas de entrevista para el puesto de Software Engineer en Front

1st Recruiter call 2nd Hiring manager 3rd Coding round which recruiter mentioned will be algorithms and leetcode however turns out it is real world problem[more like simulation of their messaging system] based questions also a miscommunication in preferred language I mentioned vs what interviewer was prepared for. Company needs to find standards on this coding round which apparently is very newly introduced round in their interview process
