First thing i got from your mail is that present day students are smart and career-oriented. Faculty need effective communication, English Language Proficiency, Good Interface with Industry and lots and lots of insights to share about life, approach and career.
From your mail, it seems your English language is not upto the mark. I am not taking you negative, but its what the current Management students' profile and expectations.
My eligibility to tell you is I worked as HR Professional, Trainer - Soft skills , Oral communication & Employability, Consulting and HR Adjunct faculty. Totally comes around 19 years of experience and exposure.
Please first convince yourself that ur management faculty. thats prime to be successful in Management Teaching and that too for present crop of students.
If i hurt you anywhere, apologies.
