He was sworn in as the chief advisor - a position equivalent to prime minister.
Women's rights activist Farida Akhtar, right-wing party Hefazat-e-Islam's deputy chief AFM Khalid Hossain, Grameen Telecom trustee Nurjahan Begum, freedom fighter Sharmeen Murshid, chairman of Chittagong Hill Tracts Development Board Supradip Chakma, Prof Bidhan Ranjan Roy and former foreign secretary Touhid Hossain are among the advisory council members.
Dhaka University Professor Emeritus Serajul Islam Choudhury said that one of the duties of the interim government would be to restore order, which has been disrupted over the last few days following the fall of Hasina.
"The other task is to ensure the safety of citizens," The Daily Star newspaper quoted Choudhury as saying after the oath-taking of the interim government. The government would also need to eliminate all forms of oppression and the culture of fear prevailing across the country, he said.
However, the main responsibility of the government, he emphasised, would be to hold a fair and acceptable election to facilitate a democratic transition of power. Eminent jurist Kamal Hossain said, "The change that has happened was welcomed by everyone. There has been an extraordinary turnout at the event. Everyone feels that change has come.
"We hope they [members of the advisory council] will be able to address the new crises. People will expect a meaningful change -- let this be that change," he said.
Barrister Sara Hossain said: "My main expectation from this government is that it will enable substantial reforms to institutions in Bangladesh and clear the path for truth-telling about what has happened not only in the immediate past or the past few weeks but even over the last 14 years and before that."
The students' anti-discrimination movement was for reforms and against repression and these should be the interim government's main themes, she told the newspaper.
"What I perhaps am a bit troubled by is that, unlike previous years, there is no balance of political background and police. We obviously have no representation from (Hasina-led) Awami League. This absence of balance could cause a problem," she said, Bangladesh has a secular Constitution, history and tradition, which has not denied any faith but encouraged pluralism, but the swearing-in today did not reflect that, she said, expressing hope that "it is not a sign of things to come."
The inclusion of students is of course unprecedented, she said, adding, "But I think it can only add energy to the whole process ... I believe they can be a part of keeping the interim government in the right direction and keep it within the demands of the students and general people. We need to remember that even post-Liberation in 1971, we had many young leaders."
Samina Luthfa, associate professor at Dhaka University, said, "While I welcome the interim government, it is to be noted that many of them are from non-government organisations and require a specific kind of skill set. However, there is much work to be done to reform the nation, whether they have the skills for that remains a question. I think including the students [leaders of the anti-discrimination student movement] in the government brings hope."
Asked whether minority and women representation were enough, she said, "I believe those could be higher. Many other women and actors from religious minority backgrounds are skilled and have been supporting the movement, they too could have been included. More people from these segments of society could have ensured a higher possibility of a 'discrimination-free' country."
She added that since the Jamaat-e-Islami was banned, the Hefazat Ameer may have been included to balance out participation from all religious backgrounds.
"We are in an extraordinary situation and of course, we cannot expect everything to be perfect already, it will all take time.
"However, at this moment, the first thing the interim government must look after is the safety of all citizens, justice, the economy, and restoring law and order."
