单选题 For London-based Michelle Brideau, 10 years in the travel industry felt like an eternity. What started as low pay and high stress—but great perks—had evolved into low pay, high stress, no perks and lots of competition from the internet. Brideau was ready for a change. She considered running a mobile coffee cart for commuters in her neighbourhood, but the idea of London winters spent outside quickly nixed those plans. She decided on a career in technology. The problem: no experience. At some point in almost everyone's career comes the desire to change fields and try something completely different. But one of the most common stumbling blocks to making a dramatic career change is a lack of experience in the new field. Gaining that experience often means taking what can be felt like a giant step backwards in your career, whether it's by re-entering the students' world or signing on for an internship. Choices like these can be financially draining in the short term, but the long-term hope is that they will pay off before too long. Brideau needed to learn to code if she was going to launch a career in technology. But she'd been under the impression it would take years of schoolwork to learn what she needed in order to make the switch, she said in an email. Then she heard about the Makers Academy, a highly selective coding program in London that teaches web development. The intensive 10-week program, (it now costs ￡7200 and is three months long) meant Brideau was studying code whenever she 'wasn't eating or sleeping.' With the coding experience under her belt, Brideau spent two months looking for the right job or internship. 'I made sure to get out into the developer community as much as possible: meet ups, events, conferences, job fairs and such,' she said. 'I also went to interviews, was invited to do code exercises as part of the job application process, and I continued to study at home.' Eventually, through the connections she made, Brideau landed a six-month paid code-writing internship at London-based Enternships, which placed students and recent graduates in positions with starts ups and small businesses. Once her internship is over, she hopes to find a position as a junior coder. 'The hardest part was taking the leap to doing something so completely different than I have ever done previously,' said Brideau. She likened it to the move she had made from Canada to the UK. 'You keep moving forward with a lot of unanswered questions not knowing how it will all turn out until one day you find yourself at home in your new surroundings.'
