Irish professional culture is relatively informal and conversational. Relationship-building matters, and less hierarchy is assumed than in many Indian workplaces.
Networks carry unusual weight, and this is structural rather than cultural. The HEA Graduate Outcomes Survey found that for internationally domiciled graduates, recruitment sites were the most common route to a job at 21%, followed by social media and professional networking sites at 20%. Across undergraduate honours graduates overall, having already worked somewhere including through work experience accounted for 21.1% of jobs, and personal contacts 20.6%.
Read that as instruction. Internships, placements and networks are not supplementary to the job search in Ireland. They are a large part of it, which is why placement provision is a shortlisting criterion in 4.4 rather than something to think about in your final semester.
Climate and adjustment. Ireland is mild, wet and grey for much of the academic year, with short winter days. On a one-year Master's the adjustment curve often coincides with the academic peak in the darkest months. Plan for it as you would any other known variable.
