I often happened to conduct various negotiations with both private clients and large institutions such as Larsen&Toubro and Reliance Infrastructure. I must confess, it is not simple. Especially at first. And that is why:
- their English is hard to understand;
- Indians are very attentive to details and numbers;
- for the negotiations not to be a waste of time, you will have to take care of the Minutes of Meeting or the Memorandum of Understanding in advance to document actual agreements, or issue a Purchase Order to confirm that the transaction will take place.
Now, attention. There is no corruption in India. The widespread opinion that everyone here gets kickbacks is a complete lie. So never discuss these issues with anyone. If the client wants a commission, he will take the initiative himself, and you will officially (!) pay the amount based on the transaction results.
Also don't talk about religion, don't criticize dirt or unsanitary conditions. Even as a joke. It may be rare, but it still happens that the locals take seriously what is supposed to be a joke.
