Infobip Pre-Sales Engineer interview questions

Having read many of the interview and feedback reviews, it appears that Infobip like to Ghost candidates. I had a call with the in-house recruiter who said I met all the requirements and would hand over my application to the hiring manager - expect a call he said. 3 weeks later not a single call or answer from the recruiter or hiring manager.

The interview process began with a GD. The shortlisted students had a technical and HR interview. The selected students then had to work on a case study and an idea task and prepare a ppt for the same. The ppt was to be sent to the manager's mail I'd. Selected students had to go to the company and give a presentation on it.
