Goldman Sachs has ramped up recruitment of junior bankers amid a surge in workload after a leaked survey of new analysts highlighted an increase in stress and mental health issues.

An informal survey passed around among 13 new recruits detailed brutal hours as well as claims of being shouted at, unfairly criticised, ignored in meetings and overworked. Goldman analysts have worked an average of 98 hours a week since January as deal volumes have spiked, the survey respondents said.
