Assistant-CSS
css assistant is the best if u want assistant..moreover css added benefits are: u will go to 2 fully paid trips during training all at govt expense..mind u govt provides 3 star-4 star hotels..then at each level of training , ul get these paid trips..from assistant to SO,from SO to US,and from US to DS, the trip is to a foreign country free paid by govt..and as the news now is hot that u can become SO in 3 yrs , i think u can go for CSS assistant..baki Inspectors is always good as compared to CSS..money wise u knw that..but in assistants , CSS is the best..in css when u have limited departmental for SO , u have vacancies like 200 , 250 etc..in other places like MEA or railways ul have 5 ,10 etc..so promotions are faster in CSS...css offers u wider variety of postings like LAW,consumer affairs, home,finance,education ,civil aviation..sao ur scope of work and knwldge is huge.
But Yes files files and files and then more files..but 3 hrs of work daily..from answering stupid RTI of people to Cabinet note making to answering parliament questions to working on daily receipts..its like u given the project ..and u made the dealing hand..nw report the problem in short abt the project and tell ur recommendations wat can be done..if ur seniors like they will accept it or else they will tell their own decisions etc..this is css work..
then total gross salary of CSS is: 32 in hand+ 5500 pf+ LTC+ medical(CGHS)+ training tours

Assts other than CSS :

An Assistant (General) is supposed to be posted generally 3 years in India and 3 years in foreign; and like this throughout his tenure of service whereas an Assistant (Cypher) is posted 3 years in India and 6 years in foreign; and like this
Assistant in Railways

assistant in railways: gud job ,ul get 1 pass for family ( to and fro) anywhere in India free and 3 passes for family (to and fro) in which u pay 1/3rd of amount..all this for tier 2 AC ticket..then railway has its own railway homes all over India ..so u can stay there at a very cheap rate..if u are using railway passes..
The prob is in CSS you will be entitled for plane tickets as you become under secretary..but in railways AC tier 1 ..no plane tickets..then CSS offers u wide variety of postings in different departments..but in railways , only 1 department..
railway tickets passes which I mentioned are every year..after 3 yrs of service , u will get 3 free passes every year to any part of India with family ,where u can use railway homes..but I think railway homes can be used only once u become Gaztd..(I am nt sure on this)..
railways ki posting lucknow bhi ho sakti hai..CSS is all Delhi..and always delhi..

Assistant gets promotion to the post of section officer,that too after qualifying 6 papers in an exam conducted by upsc, then under secretary, then deputy secretary and they retire after it,lucky guys go up to joint secy level
assistant other than css is nt all delhi plz..it may be lucknow 2..or some other state..css is all delhi..
the problems with assts other than css is that promotions are pretty slow there..as when departmental exam is there , only 12-14 vacancies for SO are there..but in CSS one can see 300-400 vacancies as per prevailing records.

Assistant in MEA & assistant (Cypher) in MEA :

MEA has problems in postings and then govt gives u not much amount in dollars to spend outside..even if they give 1500$ per month in a foreign nation ,they are nothing when u go to a foreign country..moreover postings are also at odd places..and Cypher has night shifts 2..and its like u have to work for 6 days and then 2 days off. and 2 days will be nite shift..so no sat sun like system..
Most sought Assistant post under CGLE due to charm of foreign posting and many other lucrative facilities like children's education, accommodation etc and a very handsome salary of more than 1 lakh per month (perhaps upto Rs 1,25,000). But one can be posted in countries like Afganistan, Pakistan, Irak, Libya too. Cyphor Asst. is little different from Asst. (general) because they have to do the task of coding and decoding in addition of some highly confidential language. Cypher Asst get more foreign posting than general Asst but the promotional avenues are better in General Asst. Overall in MEA, the promotional chances is very less and one can go up to the level of US. one can get his first promotion after about 15-17years if he will not clear departmental examination and after clearing departmental examination, it will take around 8 odd years.

Preventive Officer (Customs Officer) :

The next promotion of preventive officer is superintendent of customs which is a gazetted post...it takes around 7-10 years to get the first promotion...and then next promotion of supdt. of customs is assistant commissioner i.e. IRS...however the second promotion takes a lot of time...and some people don't even get the second promotion!!
preventive officer is a uniformed post...
