Excerpted from the Russia Career Guide
Take several copies of your résumé/CV (in both Russian and English/other language) and personal documents (photo ID, diplomas, letters of recommendation, certificates, awards, PowerPoint presentations and business cards) to the interview. Other documents may be asked for and could be of help during the interview, but this generally will not happen at the first meeting.
Usually the job interview is conducted in Russian, and it is highly advantageous if you speak Russian. This is especially important for Russian companies where a limited number of people speak other languages.
In general, the individual interview will take 40 to 60 minutes and is held in a separate meeting room. The style of the interview will depend on the specific company, the position, corporate policy or sometimes even on a specific interviewer’s preferences.
At the end of the interview, it is appropriate for you to ask when the results will be shared or when it would be acceptable to make a phone call to inquire about the process. Writing a thank you letter on the same day as the interview is not necessary if both parties have agreed to be in touch in a couple of days; however, if the interviewer asks for a week or more to get back in touch with you, it is advised to write a thank you letter the same day.
This is just a sample of what you'll find in over 100 pages of information in the Russia Guide.
