VertexCGI organised a group interview and invited ~80 candidates for 1 call, asking every person to tell others about themselves and why they want to work in VertexCGI. Afterwards, after almost 2 hours speaking, they took 15 mins break and mentioned ~7 people for the second round, asking basic questions like "what is your main achievement"; they didn't let them ask any questions about the company. I wouldn't recommend to apply for this
