The problem
Fresh graduates and working professionals in Bangladesh struggle with technical interviews for roles like web developer, app developer, software engineer, machine learning engineer and backend engineer.
Local companies use hiring approaches that generic preparation material does not cover, and there is no structured mock interview platform tailored to a specific role, industry or company.
What we deployed
Mock interviews conducted by professionals working at top companies, focused on company-specific and position-specific requirements.
Career-based technical courses including MLOps, LLM/NLP and research methodology, led by working practitioners.
Career development sessions covering both technical and soft skills for longer-term preparation.
What changed
Over 50 mock interviews conducted in the pilot, with 85% of participants reporting improved preparation and confidence.
The first live MLOps course completed with more than 45 students in the opening batch and strong feedback.
Commercial model
Initial margins are projected at 25–40% during the pilot phase.
Technology used
A web-based mock interview system, a learning management system for the courses, AI-powered feedback and analytics on candidate performance, and a secure payment gateway.
Business growth potential
Bangladesh produces thousands of computer science graduates a year and no platform offers company-specific mock interviews. The addressable groups are freshers preparing for a first job, professionals switching into ML, AI or software engineering, and experienced engineers targeting senior roles at top companies.
What comes next
Widening the catalogue beyond software and ML into cybersecurity, frontend engineering and cloud computing.
Market differentiation
Domain-specific rather than generic: interviews and courses shaped to particular industries. Instructors are practising ML engineers, AI specialists and lecturers. The offer combines technical training with career and communication coaching rather than treating them separately.
Market strategy
Exclusive partnerships with universities and training institutes, and a delivery model that scales, online live sessions, recorded content and mock interview simulations rather than one-to-one coaching alone.
Feedback
85% of pilot participants confirmed they benefited from the mock interviews and courses. The first live MLOps batch reviewed the course well for being practical and interactive rather than lecture-led.
