OmniBridge Software Developer interview questions

Time wasting process. They took 4 rounds And never get back to you even after follow up. First round was technical telephonic round. After that 1 hr written test. Then Managerial Round After that round with VP. I gave four rounds and never heard back. After 1 week I sent feedback mail to HR but she never replied to it. People are investing their time for the interview process. At least gave them proper feedback
