“Quotas are a discriminatory system,” the 26-year-old added. “The system has to be reformed”.
The current system reserves more than half of posts, totalling hundreds of thousands of government jobs.
That includes 30 per cent reserved for children of those who fought to win Bangladeshi independence in 1971, 10 per cent for women, and 10 per cent set aside for specific districts.
Students said only those quotas supporting ethnic minorities and disabled people – six per cent of jobs – should remain.
Critics say the system benefits children of pro-government groups, who back Prime Minister Sheikh Hasina.
Her father, Sheikh Mujibur Rahman, was Bangladesh’s founding leader.
Hasina, 76, won her fourth consecutive general election in January, in a vote without genuine opposition parties, with a widespread boycott and a major crackdown against her political opponents.
Critics accuse Bangladeshi courts of rubber-stamping decisions made by her government.
The system was initially abolished after weeks of student protests in 2018.
But in June, Dhaka’s High Court rolled that back, saying the cancellation had been invalid.
Hasina has condemned the protests, saying the matter had been settled by the court.
“Students are wasting their time,” Hasina told female activists from her party on Sunday, Bangladeshi newspapers reported.
“After the court’s verdict, there is no justification for the anti-quota movement.”
Protests began earlier in July and have grown in size.
“We will bury the quota system,” students chanted on Sunday in Bangladesh’s second city Chittagong, where hundreds of protesters marched.
In Dhaka, hundreds of students disrupted traffic for hours, police said.
At the elite Jahangirnagar University, at least 500 students blocked the highway connecting the capital with southeastern Bangladesh “for two hours”, local police chief A.F.M. Shahed said.
Bin Yamin Molla, a protest leader, said at least 30,000 students participated in the protests, although the number could not be verified.
Bangladesh was one of the world’s poorest countries when it gained independence in 1971, but it has grown an average of more than 6 per cent each year since 2009.
Hasina has presided over that breakneck economic growth, with per capita income in the country of 170 million people overtaking India in 2021.
But much of that growth has been on the back of the mostly female factory workforce powering its garment export industry, and economists say there is an acute crisis of jobs for millions of university students.
