Teacher

Good morning Marom! As a CTO and co-founder, you must have a lot on your plate. How are things going?

M
MaromTracking

Yes, very busy! This week she have many meetings with potential investors about our global markets expansion.

Subject-verb agreement

she have → she has (90% error rate)

T
Teacher

That sounds ambitious! How do you feel about the pressure?

M
MaromTracking

The opportunity is exciting but I made much mistakes in my last pitch. The feedback was much more along than I expected.

Countable/uncountable + Comparative

much mistakes → many mistakes | much more along → much more than (80-85% error rate)

T
Teacher

I understand. What specifically happened in that presentation?

M
MaromTracking

I have been there yesterday and struggled to manage expectations about our financial stability.

Tense selection

I have been there yesterday → I was there yesterday (70% error rate)

M
MaromTracking

But I feel gratitude for the experience. It helps me prioritize what's important.

Emerging vocabulary

Good use of 'gratitude', 'prioritize', 'financial stability' - needs more practice

T
Teacher

That's a great attitude! How do you plan to adopt these learnings?

M
MaromTracking

I need to adapt... or adopt? I always confuse these. I want to be more appreciative of the feedback.

Struggling vocabulary

Confusion with 'adopt vs adapt', 'appreciative vs grateful' - requires teaching

T
Teacher

Let's work on that! Can you tell me about your interests outside work? I heard you like sports.

M
MaromTracking

Yes! I love football and paddle. It's like a metaphor for business - you need to persevere and stay confident under pressure.

Active + Struggling

'confident', 'pressure' used naturally | 'persevere' still developing

M
MaromTracking

On weekends I build Lego with my kids and do Pilates. It helps with work-life balance and efficiency.

Interest alignment

Topics match profile: Lego, Pilates, work-life balance
