GS — Initially I was much slower than my colleagues. After 18 months I was 80% as fast as them. Everyone needed to learn and memorize lots of details in a big system. Without that "mileage" you can’t be as fast as the rest.
I relied on my colleagues to give me pointers and detailed explanations. Otherwise it was too many details to wade through by one self.
Citi — no comparison — No "team mates" per-se. I had two old-timer colleagues who were very familiar with the system. I was not benchmarked against them.
I didn’t need to understand the ins and outs of the 5-year old codebase. I never became productive with it.
95G — not slower — i joined this greenfield project from beginning (luckily). I was as fast as the other consultant. Also, I designed a few key components, so I had the "original designer" advantage.
Barclays — not slower — i joined this greenfield project from very beginning (luckily), replacing a half-finished c# system. I had very few "team peers" to benchmark against. I designed one of the most valuable and complex components, so I had the "original designer" advantage. Huge advantage. I basically name my price when it came to effort estimates.
I did read some old code to replicate the logic, but I was fairly fast, and no team member ever read the same codebase anyway.
OCBC — not slower — I was seen as slower, but actually I became 70% to 90% as fast as the other team members. I had to spend many long hours on the existing codebase but it’s a small codebase (1 man-year) so I was able to get a hang of it over a few months.
I also designed some minor modules, where I had the "original designer" advantage. The other c# developers had to come to me and understand my designs.
Stirt — I was much slower than the old-timers, but I was not slower than the new joiners. I should have given up earlier. It was hopeless. Codebase was rather opaque and you need to ask many people to understand it.
Other new joiners seemed to ask only within their own team, but I stick out my neck and asked all around my team. It may have made me look slower and /greener/, but I was trying to learn faster. Did I learn faster than them? Not enough time to show.
Macquarie — The benchmark was my predecessor + my boss. I think I was much slower than them. My boss only complained about it in the 2nd year, months after paying me a small bonus.
ICE — not slower — I’m probably faster than some team members. I feel confident how fast I can figure things out now. There are many team members to compare, so from Day 1 it was crucial to meet the average standard.
