As the ZOC team grew in strength, in 2013 ZOC launched a chain of its own exam centers affiliated with Pearson Vue in almost all major cities in India, viz., Mumbai, Pune, Bangalore, Hyderabad, Delhi, Bhopal, Lucknow, and Chennai. Consequently, almost all major certification examinations of some of the leading international accrediting bodies could now be taken by the students of ZOC at its own exam centers. Over the years, many corporates operating in the IT, telecommunications, banking, finance, and pharmaceutical industries have graced the client base of ZOC.

In 2015, ZOC diversified into providing staffing services on both an on-roll and off-roll basis. Further inspired by the overwhelming response and in keeping with the needs and demands of its clients, in 2017 a new service of providing guidance in doctorate research was introduced. With this, ZOC now covers an entire spectrum of milestones in professional education.

Established on a national level, it was time then to tap into the international market. In 2018, ZOC stretched its legs to provide e-learning facilities to clients in the North American and Middle Eastern IT dominated regions of New York, California, Florida, Texas, Doha, Qatar, Riyadh, Bahrain, and so on. Since 2019, parallel to its classroom-based training programs, ZOC has also developed fully virtual training programs that can be paid for and accessed completely over the internet.

Since its inception, the principal motivation behind ZOC's operations has always been ensuring the professional success of its clients, no matter what their size and form. With this rationale, ZOC has now diversified into providing services in allied domains that equally affect and influence a person's career development. These services include resumé writing, interview training, job search assistance, therapy for corporates, career counseling, and mentoring.

Today, ZOC holds and is guided by the constant trust, support, and loyalty of over a hundred of its distinguished clients and patrons who stand testimony to its unwavering commitment to providing high-quality career development services to all its stakeholders.
