      Senior Software Engineer Interview

      Oct 7, 2025
      Anonymous employee
      Bengaluru
      Accepted offer
      Neutral experience
      Average interview

      Application

      I interviewed at Wissen (Bengaluru)

      Interview

      The interview process was fine overall, but it varied across different verticals. Initially, I went through four rounds of interviews and was selected. However, after the selection, the recruiter mentioned that they couldn’t match the CTC I had initially stated — even though I had made that clear at the beginning, and they had agreed to proceed. Later, I had to attend another three rounds of interviews for a different vertical. Eventually, they confirmed my offer. However, the client interview process wasn’t completed at that stage, and I had to go through two additional client rounds even after joining.
