J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez Informatica (Bengaluru) en sept. 2017
Entretien
They have called me for one full day evaluation process, there were 5 technical evaluation rounds and one HR, it was transparent and very disciplined. I was asked to sit in a room, where panel member comes in and takes a technical interview and delegates the feedback to next person, each round was about 30-60 min. Since I am a java/j2ee developer, mainly focused on core java, data structures and logical thinking. It took one full day.

Quiet exhausting and not worth it. It was 8 rounds of interview. Where in 5 were technical. 1 techno managerial 1 with director and 1 with HR. No interview was started on time. There were so many last moment changes on timings. Most interview are stretched 30-30 min even more than the allocated hours.
The whole process took 1 month. After releasing the offer letter break up. They called after 2 days that the required is freeze.
Not recommended. It’s unreliable. Thank god I didn’t drop papers at my current organization after receiving offer letter.
