One of my friend use to advice me to attend interviews every 6 - 9 months. I gave a try. I could see myself as a [Technology Lead] where I am lagging in the technical and other skills. To help my readers I am listing out few the areas where I came to know a TL has to update/upgrade. Protocols like SOAP, HTTP, TCP UML - Views (Process, Sequential, ...) UML - Diagrams (Collaboration, Communication, ...) Ajax - Internals, Architecture, Scenario, ... .NET tools - FxCop, NUnit, ... Profilers - CLR Profiler, ANTS, ... Estimation techniques Build Tools - MSBuild ASP.NET Performance Counters SOA concepts SDLC Process Unit Testing, Integration Testing, etc... EAI - BizTalk exposure Collaboration - MOSS concepts All the best!
Every action of ours will always have a reaction!
