Thank you so much @Leon !

Your advice and coaching are extremely helpful for preparations for the interviews. The timeline and pacing you helped plan worked out very well.

It kept me on the right track. The exercise on coding and data analytics you recommended greatly sharpened my skills to solve the problems during the technical rounds.

The practice to communicate project work to peers is another highlight to help me earn higher score. Again thank you so much for all your advice!

Dream Job Offer from Apple!

Hi @Leon and @Mike ,

Just wanted to share, I accepted an offer from Apple as a Data Engineer and wanted to offer a huge thank you to both of you guys.

Even though I only shared a small time with you both I benefited a lot from your platform and your mock interviews.

Some of the questions you gave during our Data Modeling with you Mike were presented verbatim.


Data Engineer at Apple

The mock interview helped me do it in the right way

I did a SQL Mock interview on Instamentor to gain a better understanding of how SQL interviews are conducted.

Leon (my mentor) came prepared with a realistic case study example tailored specifically towards the company I was interested in. Read more...

The questions and tips he provided were incredibly helpful in my preparation.

My actual interview went in a similar manner and having done the mock interview helped me do it in the right way.

Senior Data Engineer at T-Mobile

Dream Data Scientist job offer!

I've tried several sites to practice SQL and is my favorite because the questions are well-designed to focus on the most important concepts. Some of the other sites are all over the place.

With, I can focus on questions by skill level or topic, and the number of questions available is a reasonable amount to study for interview prep.

In addition, I got mentoring sessions with Leon and I was impressed at how helpful it was. Leon was calm and knowledgeable, which helped my nerves over my up-coming interview.

He really takes mentoring seriously and it makes a big difference. After practicing my SQL, I got my data science dream job!


Data Scientist

Meticulously prepared and very professional

I signed up on Leon's service and was pleasantly surprised when he helped me out personally on the website. In two mock interviews with him from, he was meticulously prepared and very professional.

Throughout the interview he provided fantastic feedback and frameworks on how to be better prepared for both technical and behavioural aspects of an interview.

He is also a very positive and friendly person and I enjoyed all my interactions with him.

Data Scientist

What made the session successful was the effortlessness in being honest around Leon.

I had my first mentoring call yesterday. The session was to be for 45 mins but lucky for me, Leon did not have a hard stop. We had a detailed discussion around my career history, career transition, stuff I’m good at and enjoy doing/good at but don’t enjoy/not good at and want to improve, not good at and not interested in get the drift). Read more

Leon listened patiently, highlighted areas I needed to work on, pointed out practical considerations, and made gentle suggestions on handling a couple of situations I had bombed (salary negotiation was one).

We covered a lot of ground and had concrete to-dos at the end of the call, but what made the session successful was the effortlessness in being honest around Leon. A mentor needs to identify what is holding the mentee back in their career, and their advice can only be as good as the inputs we give them. Leon made it easy to be authentic. I’ll keep you all posted on my journey!
