DCM interview how do I prep for technicals?

So basically, how dcm works is you are constantly following the market, and that means equities but mainly interest rate environment (in Europe its the midswap and in US is the UST) you basically need to be assesing the clients on when its a good day to launch the transaction.

Regarding technicals you should know the basics about how bonds work, as well as the main types of bond that exist. You have Capital (AT1 bonds and tier 2 bonds), Senior Bonds (in europe you have Sr Preferred and Sr Non-Preferred) and covered/secured bonds, that is for Banks. For insurance you have RT1, Tier 2 and Senior. And for corporates you have Hybrid and Senior. 

I would also try to learn a bit about how rating agencies work and the relevance they have for the issuers. 

Also know some stuff about the regultators and the capital requirements for banks, like what are they regulators and requirements. 

A question you should be able to answer is why a corporation would issue a bond instead of obtaining bank financing which will always be cheaper.

Also lookup people that is in the position yo are applying to, it will be very helpful to get in contact with an intern or analyst that works in DCM and covers a similar group than the position. 

Also, great piece of advice, show very very strong interest on the actual DCM business, do not make it seem like you want to get there to afterwards swich to the M&A side or whatever. you need to show passion for markets and say you are pursuing a long term career on DCM.. etc. 

Prior to any interview, memorize (or write down if interview is online) the main indicators US Bond, German Bond, Current Interest Rates, S&P, Gold Price and some other relevant indicators. To prepare for macro, go throught the notes of the lastest FED and ECB meetings, that will also be helpful.
