Pros

Great coworkers, adequate PTO, opportunities for learning and career progression.

Cons

Everyone is chronically overworked and underpaid. Hours are long and without any compensation for overtime. High turnover leads to uncertainty. High pressure and frequent overpromising to clients, taking on new projects without considering capacity, ambitious deadlines, and poor estimations of how long tasks should take. Poor project management - should not be using Excel and OneNote for PM at this scale. All complaints are met with platitudes. Company focuses on shiny new AI tools instead of addressing serious issues employees raise.

Thank you for your feedback. We're glad to hear that you enjoyed working with your colleagues, and received a good level of support. We recognise that the client-facing nature of our work can be pressured at times, although we very much hope that there are peaks and troughs throughout the year in terms of pressure, workload and working hours. We do our best to monitor this, but also encourage individuals to speak with their line managers if they are feeling too much pressure. If you have any further feedback about your experience of medical writing, please let me know (emma.king@costellomedical.com).

Not enough reciprocity

Pros

Interesting projects, big clients, collaborative and friendly colleagues

Cons

Even though you are told you should progress without working extra hours, there is an unchanging, intense workload with high expectations. The responsibility is put on the Analyst to feedback whether things take longer than planned, however, I found over time that my feedback was acknowledged, but mostly ignored, despite me being sufficiently experienced with certain disease areas, clients or project types to know. An Analyst is expected to work very hard and carry the weight of the work for the team, but receives very little in return (an Amazon gift card after a high grossing project is completed, heart emojis on Teams, and a tiny yearly bonus). Long-term, upper management is committed to growing the company their own way (e.g. hiring junior staff and then training them up), but this appears to have led to a requirement to conform to the mould (middle class, no multi-culturalism, etc.) in order to do well here. Recently, a diversity initiative was started, but this has just resulted in surface-level changes.

The aspects that you enjoyed about working at Costello Medical are often repeated by our colleagues and so we are glad that this was your experience too. The UK faction of our Equality and Inclusion team have three ongoing workstreams each focussing on different areas; our Cambridge Outreach team, our London Outreach team and our Internal team. Since launching in late 2020, we have already developed and run a week-long work experience programme, run many workshops with local schools and sixth forms, and joined mentoring programmes with national charities, all with the aim of encouraging students from different backgrounds to consider career paths they might enjoy. We are also working to understand the experiences of our colleagues to ensure we are fostering an inclusive and supportive atmosphere for all. In addition, we are reviewing our recruitment processes to avoid all possible biases here. Our efforts are of course ongoing and there is much more that we want to achieve but we feel we are already making good headway on these complex topics. We are sorry that you were unhappy with the rewards that you received when a member of our team. We do focus on all types of reward and have enhanced the financial value of our package substantially over recent years. As well as salaries that regularly increase (twice during the first year and then annually thereafter or more frequently following a promotion), we offer a competitive benefits package which now includes Private Medical Insurance with AXA Health. Bonuses are a more substantial part of the package on promotion to Senior Analyst/Medical Writer, and again for those in our Senior Management Team. Achievements of colleagues at all levels are celebrated through Teams and during company-wide shout-outs, something that most enjoy and appreciate.
