Sollicitatiegesprek
It was the worst interview process I have faced so far. They took total of 4 rounds (purely technical). In the start, HR said there will be 3 rounds & then later added one more round. Round 2 was taken by two people, both technical Round 3 was also taken by two people (technical + manager) Round 4: technical + some other manager I could clear all 3 rounds and was also confident about the final round. one manager said that they need someone who can do full-stack JS (React.js, Node.js, GraphQL, TypeScript) & work in Java as well. (😮while JD said React.js profile) I waited for the feedback but they didn't reply. I then followed up with the HR person, he said he will update by EOD. I again waited for another 2 days but didn't receive any response. Again I called HR to follow up, he said the job position had been put on hold.😢 I felt very bad because I was genuinely interested & prepared for every round.
