MNC VS PVT LTD VS LTD CO.

I had a very bad experience of getting a call from one of the PVT LTD company/charitable funded/in the name of sharing a part of their profits with some religious organisation.The ironical part was that they had contacted me by phone after 11 months of my reply for a job opening at their so called company/ pvt. firm a FM CG company & was interested only because of the odd product they had launched, so i feel its a challenged marketing experience with these new and near to my home (udyog vihar) ventures,   so i went their after a research,   realised to meet a professionalised atmosphere but i find  "LALA chap" establishment & i decided to meet the MD of the company after long talks with his son, how agreed with my presentation,experience,future marketing plans etc.& impressed with my plans for the expansion of the company by professional approach only,so i asked are you a decision maker which he denies and agrees to have a meeting with his MD father in 2-3 days & in between he called me twice for cross check that i would be available when his father is in good mood, so when he again third time contacted me for a meeting with his father (was co-Director in a good company by luck) i feel i had to meet one of the mannered co-director of a company & learn some thing under his gaudiness but when his son change the venue from udyog vihar factory to a resident area i felt cheated but i remembered that young boys afferets to arrange a meeting i agreed then again reaching to the address i realise i have to be centered at the meeting because it was a religious premises & so called MD/DISCORDED CO-DIRECTER who was sitting with bunch of odd people asked me very un-professional questions but because i was also with the same community i think all that bunch were also interested in our talks suddenly his son arrived and i make up my mind that might be this is a way to know my professional views only which i discussed with his son & they do`nt have any good/ lucrative opening for me. So i decided not to explain marketing plan with these cheaters, who were interesting in other company`s software (because i find they were engaged with one more firm of this group/ organisation who were into software solutions) by meeting in the name of interview they share marketing, software strategy & then make/amend their marketing plans, so i realised what is difference between a MNC where their is a process step by step you follow and company also follow some norms & private, bunch of money lenders in the name of LTD co.directors, members with family shared posts within the companies board.
    What i learned is if someone has good ideas,marketing plans,strategy views of any kind he/ she must be careful whom we meet & discussed in an interview,presentations etc.we have to have some points within our self or develop some skills to prevent our plans from these cheaters/ copy cats and there i remember one Desi comment to share "BILLI SHER CO SAB SIKHATI HAI PER PED PER CHARDNA NAHI SIKHATI".
