Mathias Willburger CEO at Millimetrika
5.0★
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.
Deekshu Gunaga Review from Google

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
Sankalp Deshpande Review from Google

Sankalp Deshpande's Review Sourced from Google
Don’t waste your time going for the interview. They’ll make you wait and then just tell you your application has been rejected without giving proper feedback Even though I have healthcare experience and cleared the relevant rounds, they still said I don’t have experience in BA. Feels like a total waste of time — waiting, interviewing, and then being rejected without proper feedbac
