One to One training with customized plan.
Facebook senior engineer, 6 years in Bay Area, experienced interviewer, specialized in coding, algo and system design。
10+ years experience in data engineering, phD in data science, Principal Engineer. Built from scratch multiple highly-scaled systems with the top companies. Specialized in system architecture and big data platforms.
Uber SDE, 4 years data scientist at hot startups, data team lead, specialized in data analysis, behavioral and presentations.
S. came from overseas. There has been a hard time for him to get interview opportunities because of his background. With our referral, he got an interview with Twitter. Shortly after his bug-free performance, Twitter issued him the dream offer.
Y was a phD student majored in Electronic Engineering who had the courage to quit the EE program in the second year and came job-hunting in the Bay Area alone. With our guidance and his diligence, Yang managed to practice each and every question on Leetcode over and over again for 5 times. In 6 months, he got the offer from Google, where he’s worked for half a year by now.
W is a new graduate from USC, who got the Yahoo Offer. He is particularly hard-working even after class. However he got average feedback from the Yahoo interviewers. When the manager was hesitating about the hire, we made an effort to connect with the team manager with our network and recommended W as being strong in coding, responsible and devoting. Eventually W was given the offer. Currently he is preparing for the next interview with other top tier companies..
X.W has some fundamental experience on coding before he enrolled in our program. He’s gone through Leetcode briefly by himself before coming to us. However a problem was found after he took our test - he was not able to cleanly implement the solutions although he knows the logic well. Sometimes the codes are buggy and not clean enough. According to his case, we created a custom course to polish his coding skill and communication. After two months of training, he got the G offer. Currently he is still striking for other offers.
Before he came to us, Z. worked at a small company in Bay Area for 2 years. The heavy workload has hindered him from preparing for interviews. Another problem is that his job relates more to hardware engineering. Therefore he was not familiar with software system design. Having had the custom course that we built for him, Z got into the stage of interview preparation. Within 4 months, he finished Leetcode off and completed the system design project assigned by us, which helped him learnt the principals in system design. He ended up with 3 offers in hand and took the one from Google.
Target:become an algorithm guru and code bug free.
