Whatmore, who finishes his four-year tenure with Bangladesh after the India tour ends on May 29, is seen as a strong contender, if not the frontrunner, to replace Greg Chappell as India's coach.
"I don't know what the future holds," the 53-year-old said ahead of the much-anticipated series of three one-dayers and two Tests.
"All I know is I will be without a job after May 29. I also know I can't afford to stay unemployed for too long.
"But as of now, I am totally focussed and committed to ensuring that Bangladesh do well in this series."
Whatmore, a former Australian Test batsman, has been regarded as one of the best in the business ever since he masterminded Sri Lanka's triumphant World Cup campaign in 1996.
He returned from the recent World Cup in the Caribbean with his reputation enhanced after Bangladesh qualified for the second round for the first time and secured wins over India and formidable South Africa.
Whatmore declined an offer by the Bangladesh Cricket Board to remain with the team, saying he was looking for 'new challenges' and even publicly declared his intention to coach India.
The Australian, however, insisted he was not in talks with either India or Pakistan, who too have advertised for a new coach following Bob Woolmer's tragic death at the World Cup.
"I have not been lobbying," he said. "I don't go promoting myself. I have not sent my application to the Indian board as has been said.
"I have also not been formally approached by the Pakistan Cricket Board. Somebody spoke to me on their behalf during the World Cup asking for my contact details but I have not heard from them since."
When Chappell quit India after the disastrous World Cup campaign, the Indian board appointed former captain-turned-commentator Ravi Shastri as interim coach for the Bangladesh tour.
Shastri is also on the seven-man panel of the Indian board that will pick Chappell's long-term successor in time for the tour of England and Ireland starting in June.
Shastri is expected to gather feedback on Whatmore, or speak to him directly, during the tour to gauge whether he fits India's requirements.
All four Asian Test teams could be looking for a new coach if Tom Moody decides to quit World Cup finalists Sri Lanka.
Moody will discuss his future with Sri Lankan officials in mid-May after a brief holiday in Britain amid speculation he may return home as coach of Western Australia.
Sri Lanka-born Whatmore played seven Tests for Australia in 1979 as a top order batsman before taking up coaching, making his mark with Sri Lanka's World Cup win.
He also coached English county Lancashire and had another stint with Sri Lanka, before taking up the challenge to transform Bangladesh cricket in 2003.
Under Whatmore, Bangladesh secured their lone Test win over Zimbabwe and won five one-dayers against established teams, including world champions Australia, South Africa, India (twice) and Sri Lanka.
