SayOne Technologies Software Engineer Java Developer interview questions

Here, I had 3 rounds of Interview such as HR, Technical and then Final round with CTO I comfortably cleared HR round and technical as well But in the HR round , the questions are all basics but I have prepared something really really hard but whereas the questions are all came from a basic fundamental level , out of hesitation I have answered lot of questions wrong at that moment, This is what a bad day can cause to you but the overall process was totally enjoyable and meaningful debate with their team , I really missed a golden opportunity to work with them, Yeah I regret
