Vantaggi
Technologies stack depends on team but new technologies are quite common, legacy things in process of elimination. More or less flexible schedule, modern software/computer/office. Decent salary. Whole bunch of talented people.
Svantaggi
Processes management is worse than bad, it does not exist at all, no schedule, constant overtimes as consequence of poor planning, chaotic decisions without direction. Low working culture, no respect for private life, high pressure. No diversity, most of people are from South India, technical discussions in Tamil are regular thing despite of some team members are not Tamil speakers. Very often people are hired not for their skills but for their loyalty / private connections. Nepotism and lot of internal politics which affects performance and delivery.
