‘The team is extremely commercial. I have also found their relationship building extremely effective – they do not interact at a transactional or task level, but at a human level.’

‘Years of working with our company gives them deep institutional knowledge. It’s amazing to have advisors who know when I’ll be stuck in the investment committee and can just got on with things.’

‘The team, overall, is very collegiate, helpful, engaging and friendly.’

‘The Sidley team is highly experienced and able to bring novel ideas to bear in complex transactions and negotiations. This experience runs deeper into the organisation than I would typically see at other law firms.’

‘ Fatema Orjela is a gifted and natural leader, as well as being a highly competent lawyer. What makes Fatema stand out is her ability to operate at 5mm and 30,000 feet – she has an extremely strong grasp of the detail but maintains a commercial perspective. As an advisor, while one would consider this a standard requisite, it is very rare. Fatema is also very effective at simplifying the complex and communicating very clearly. Her ability to build relationships and increase the value of the sum of the parts of her network is second to none.’

‘Eleanor Shanks gives full dedication to her clients. I fully trust her.’

‘Fatema Orjela has a fantastic approach to client service. She keeps in regular contact with her clients to ensure she can get ahead of issues, and provides and sources excellent support. She has an “ask me anything” approach that makes clients feel very comfortable with her and confident in her skills.’

‘Adam Runcorn is a fantastic rising star, great mastery of both the legal and commercial side.’

Sidley and Sidley Austin refers to Sidley Austin LLP and affiliated partnerships as explained at

The Lex 100 Verdict

Known for its finance prowess and high-profile transactional work, Sidley Austen has ‘friendly, down-to-earth people’ and a ‘wide range of practice areas and quality work'. Trainees applaud the firm’s ‘office culture’ and 'international reputation’ as well as appreciating the ‘growth in London, culture and quality of work’. Again a Lex 100 Winner for remuneration, Sidley Austin consistently is at the upper end of the pay scale among City firms. The small intake receives ‘less structured training’ but ‘more responsibility early on, learning as you go’. Smaller teams ensures that trainees get ‘more heavily involved in transactions’ and prove to be a real selling point for the firm. Trainees complained of ‘tough hours’, particularly with the added strain of working those hours from home during the pandemic. Also some complaints concerned perceived ‘overreliance on recruitment from Oxbridge’ and ‘fewer international and client secondment options’. Highlights of training include ‘working on a high-profile UKSC hearing and winning the firm's annual pro bono prize’ and ‘the firm's 'European Lawyers Conference' which offered a fantastic opportunity to meet everyone else at the firm in different teams’.
