I applied online. I interviewed at Cognizant (Hyderābād) in Mar 2019
Interview
it was a walk-in and called for technical round after 2 hours. i was so disappointed with the interviewer, he just asked me only 3 basic questions and i answered him in detail and also explained about current project and then finish. i didn't understand how one can come to a conclusion so easily.

Interview
Nunca en mi vida me había sentido tan mal en una entrevista.
Me la hacen dos personas, dos chicos que trabajan allí. Empiezan con una serie de preguntas genéricas de Machine Learning, una de ellas sobre: Qué es el overfitting.
Respondo perfectamente, tanto que me dice que CREE que me he inventado la respuesta y que debo haberla mirado en internet o me la debo haber aprendido de memoria (qué ironía). Así que dibuja dos líneas en un cuaderno y me pide que interprete en directo si es overfitting. Le comento que no lo veo bien y tal y me suelta directamente: "Entonces no sabes qué es el overfitting".
Simplemente espectacular.
El resto de la entrevista transcurrió en la misma dinámica. Gente MUY desagradable. Nunca había visto algo igual. Todo el rato en una dinámica completamente tóxica de entrevista que merece que a esas dos personas les den un toque completo de atención porque vaya vergüenza.
