J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Wissen (Mumbai) en avr. 2026
Entretien
There were total 4 rounds. 2 rounds taken by Wissen panel and 2 rounds by clients.
I had cleared 3 rounds but because I couldn't appear for the last client round due personal emegencies my profile got rejected.

Question 1
1. Internal working of hashmap
2, Difference between innermap and identity hashmap and concurrent hashmap.
The interview process was fine overall, but it varied across different verticals. Initially, I went through four rounds of interviews and was selected. However, after the selection, the recruiter mentioned that they couldn’t match the CTC I had initially stated — even though I had made that clear at the beginning, and they had agreed to proceed.
Later, I had to attend another three rounds of interviews for a different vertical. Eventually, they confirmed my offer. However, the client interview process wasn’t completed at that stage, and I had to go through two additional client rounds even after joining.
