      Web Development Review from Mathias Willburger

      The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.

      suresh's Review Sourced from Google

      Candidates should carefully evaluate whether to participate in this interview process. Based on my experience, it seems the interviews are being conducted primarily for showcase purposes rather than actual hiring, leading to a significant waste of candidates' time, preparation, and effort.

    • Deekshu Gunaga
      Deekshu Gunaga Review from Google
      1.0★

      Deekshu Gunaga's Review Sourced from Google

      Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience
