Janda played 10 times for his home country, and in his participation with the Czechoslovak Olympic team at the 1920 Summer Olympics football tournament he was notable for having scored two hat-tricks and appearing in the final.[3] However, he did not win a medal; after the dismissal of his team-mate Karel Steiner in that final against Belgium, Janda and the other discontented Czechoslovakians left the pitch in the 40th minute, ultimately causing the Czechoslovaks to get disqualified.[4]
