Great session with Dennis. During our session he actively gave precise feedback about interview structure, the quality and efficiency of the conversation, and important signals to pay attention to. The feedback was level-appropriate and rooted in years of experience across several top-tier tech companies. After my session, I had a very clear sense of where to focus my efforts and practice. Thanks Dennis - I hope we get to work together again soon in this capacity!

I had great time with Dennis's session. He gave in-depth knowledge in the industry and provided guidance based on my needs. One thing I didn't expect was that he boosted my confidence. Look after and recognize myself. I highly recommend him. Hope you will improving your self-esteem and increase your confidence as well.
