I was good experience for 1st technical round. 1. Interviewer will asked about what you have done previous projects and some questions on that. 2. Not much coding interview but interview want candidate has knowledge or not or his capable or not to do this thigns. 3. If you are reactjs developer then life cycle methods and hooks in depth you need to prepare. 4. There product is on vue.js but you know javaScript then you will easily solve problems. 5. Interviewer will give you scenario base questions on SQL queries like join, sorting etc 6. performance related questions.
