I replied to your questions below.
1. What are the best preparation materials for PST (for example), Case Interviews, FIT and etc? Case in Point may be outdated? Some free online cases might not guarantee their quality? etc... So, could someone recommend some high-quality materials?
2. What is the most efficient plan? Like the overal plan, how many hours should be devoted to which part, and how to prepare for each part, etc
I would recommend the following steps to organize your preparation:
- Identify the companies interesting for you. Many people are interested mainly in MBB, you can start defining the exact list of companies interesting for you for the internship
- Define a calendar for your preparation. Check if there is any deadline for the internship applications. Then identify how many hours you have before that and allocate a time slot for preparation in your calendar for each day, working on the points below. Many people need 100+ hours to be ready before the interview so you can keep that as a benchmark
- Read Case In Point or Case Interview Secrets for a general understanding of what a consulting interview is. Don’t focus on the structures proposed in the books though, as they are not good enough nowadays.
- Start reading good MBA Consulting Handbooks – you can find several for free online (Insead is a good one to start). Read the cases and try to apply your structure to solve them. Whenever you see there is something missing, upgrade your structure with the new insides. PrepLounge also has a Case Library that you can use. Try to read at least a new case per day – in this way you will absorb better the information with constant learning.
- After the first 5-10 cases in books/handbooks and basic theory, start to practice live. PrepLounge can be helpful to connect with other candidates for that. There is a relevant part of the interview score that is based on your communication, which you cannot practice at all if you read cases only. Keep track of your mistakes and see if you repeat them. If so, try to identify the source of the mistake (feedback of experienced partners would be particularly useful for this). Be sure to focus on both the behavioural part and the case part. The case part should also cover market sizing, mental math and graph analysis.
- Before your application, be sure to review your CV and Cover, so that they are in the required format for a consulting application
- At least three weeks before the application deadline, start networking to find referrals for your target companies. You can find some tips on how to do that here: https://www.preplounge.com/en/consulting-forum/hey-everyonehope-all-is-well-3176
- Once you feel you are not improving anymore, if you have a tight time constraint or if you want a realistic assessment of your level, consider using support from experts to strengthen your performance
- Before the interview, be sure to prepare your questions for the interviewer –great way to show you prepared in advance and to connect with the interviewer for a good final impression.
3. One of my target company is McKinsey, i heard from a recruiter from McKinsey that they've replaced the PST test with the game accessment already in London office, could someone tell me more about this game accessment and advise me how to prepare for it? Plus, except London, does Shanghai office has also replaced the PST test?
I have some specific material to prepare on the Imbellus, please feel free to PM me for more information. Until end of 2019, Shanghai still had the PST – not sure if they changed in the very last months
4. If i apply for Shanghai office, will the interview be carried out in English or Mandarin?
Normally interviews are always in local language, plus they may check your English with some questions
