Career coaching
This was the most informative, helpful session I could imagine. Sergey offered advice in all levels, from what are the reasonable next steps for my career, to how recruiters make use of information in my CV. I am as grateful about his high level advice of next career steps, which made all the sense to me, to his answering all my technical level questions on how to prepare a CV and how to optimize my strategy for applications. Could not be more useful, I highly recommend, and will book further sessions myself.

Apart from the mock test, Sergey was very helpful at narrowing down the likely scope of my upcoming interview and the motivations of the hiring manager.

Sergey’s coaching services are indispensable. The value-add that he delivered in our short one-hour session was by far the most helpful feedback I’ve received, minute-for-minute, in my professional search. Not only was he able to provide a detailed and exclusive peek into the company’s hiring processes, but he was also able to expertly tailor his perspective to my background and desired professional trajectory. I would highly recommend Sergey as a coach and professional mentor.
